Leak memory in the Convolution

• leak memory with the callback function

  Hello

  I'm pretty new on LabWindows and library ninety, I worked mainly with LabVIEW.

  I am trying to create a basic c++ client (no GUI) that sets up subscriptions to several network publication of a PXI DAQ data variables.

  The data for each variable is sent in a cluster and contains different types of data with a 2D array large int16 for the acquired data (average size of array is 100 k in total, and the average time between the data being sent is 10ms). I have an average of 10 of these variables DAQ.

  I'm passing the same callback function as an argument to all of these subscriptions (CNVCreateSubcription).

  He reads all the correct data, but I have a problem is that I have a memory leak in the callback function in the CNVCreateSubscription.

  I have reduced the line of code one and found the function that actually causes the memory leak, it's a CNVGetStructFields(). At this point in the program data has not yet been adopted for the variables of the customers.

  It is a simplified version of the callback function, where I just unzip the cluster and get data (showing only a field in the cluster in the example, showing also doesn't not the decleration).

  The function is passed in the function to subscribe, as follows:

  public static void CNVCALLBACK SubscriberCallback(void * handle, CNVData data, void * callbackData);

  CNVCreateSubscriber (url.c_str (), SubscriberCallback, NULL, 0, CNVWaitForever, 0, & Subscriber);

  public static void CNVCALLBACK SubscriberCallback(void * handle, CNVData data, void * callbackData)
  {

  int16_t daqValue [100000];

  unsigned long int nDims;
  unsigned long int daqDims [2];
  CNVData fields [1];
  Type CNVDataType;
  unsigned short int numFields;

  CNVGetDataType (data, & type, &nDims);)
  CNVGetNumberOfStructFields (data, & numFields);
  CNVGetStructFields (data, fields, numFields); //<-------HERE is="" the="" problem,="" i="" can="" comment="" out="" the="" code="" after="" this="" point="" and="" it="" still="" causes="" a="" memory="">

  CNVGetDataType (fields [0], & type, &nDims);)

  CNVGetArrayDataDimensions (fields [0], nDims, acqDims);
  CNVGetArrayDataValue (fields [0], type, daqValue, daqDims [0] * daqDims [1]);

  CNVDisposeData (data);

  The average settings, I use all my memory systems (4 GB) in time.

  My question is, all else have experienced this and what might be the problem/solution to this?

  Thank you.

  I see that you disable only handle memory (data), but not the memory of the structure; Therefore, before calling CNVDispose (data) you should have something like

  While (numFields > 0)
  CNVDisposeData (fields [-numFields]);

• Will be the leak memory for the queue when it is used in producer and mode of consumption data acquisition transfer different size table.

  In data acquisition, I use a loop to query the data from the hardware, another loop to receive the data from query sent by queue loop.

  Each time the size of the transferred data matrix is perhaps not the same, so the system can assign different table size and recycle frequently.

  It cost memory leak. Or it will slow down the performance, given that the size of the array is not fixed, so everytime need to create a new array of size.

  Any suggestion or the best method.

  If I understand your description, your DAQ loop acquires data with the parameter of the function of reading-'1 ' for reading at the DAQmx samples. This translates into different picture sizes.

  Passage of these tables directly to a queue is valid and she didn't mind important in performance (at least AFAIK) and it certainly does not leak memory.

  So the question is more or less:

  It is valid that the consumer receives sizes different picture for analysis? How your consumer manages these tables?

  hope this helps,

• Leak memory in the routine of Winhttp 6.1 WinHttpSendRequest() on Windows 7

  I posted the following question in https://groups.google.com/forum/# microsoft.public.winhttp! Forum/Microsoft.public.WinHTTP with the subject 'leak memory in WinHttpSendRequest()'.

  I think that this function of WinHttpSendRequest() still leaks memory in Windows 7 (WinHttp 6.1), here is what I have:

  Platform: Windows 7 Enterprise (version 6.1 SP1) 64-bit platform.
  WinHttp: version 6.1.7601.17514.
  Visual Studio version: Microsoft Visual Studio Ultimate 2013, Version 12.0.31101.00 update 4.
  Memory tool leak detection: performance, using "private bytes".
  Symptom: With WinHttpSendRequest() call memory continue to increase even if it looks like a square, but the trend going upwards. Without calling WinHttpSendRequest, the trend is pretty much flat line, even if it looks like a square.

  Here's the code,

  After getting the leak memory, look at DropletEventServlet in the Navigator component of/dyn/admin, and you can see the accumulation of mappings element of the page in question form. DropletEventServlet is a component to extended global (regardless of the scope of managers form she monitors) and does not remove the entries over time (which is why it is important to not use IDS in the form element cards FormHandler, and he issues a warning once you 500 for a form).

  My guess is that the bug you see is a fixed bug CCS been resolved in more recent versions of the ATG (2007.1 and later versions). You can see a newer version of the ATG to see if the form is always encoded in the same way.

• Leak memory in the rings image under Linux

  Hi all

  I have a very serious problem, that I didn't have in the previous version of my app and one of the only addition I've done is to use the rings of the image. The app uses 6 MB more every minute. If I remove the rings, it stops. It could be a bad lead, so I'm writing a test case, but is there that a list of memory identified leaking somewhere?

  Thank you.

  Hello William,.

  I've studied this and confirmed what you see. There is indeed a very serious leak in the Linux module. I'm really sorry for the inconvenience that was done to you. We have created an internal bug reported for this question (414435) and it will be fixed soon.

  To answer your last question, it is not yet a more recent version of Linux than 2010, but there will be an update to the Linux module later this year, and it will include this fix.

  I have not yet studied the issue with CanvasDrawPoly, but I'll do it soon.

  The error with anti-aliasing is expected since this feature has been added in 2012.

• leak memory in the dll with a function imaq

  Hello

  I'm writing a dll that uses the imaqImageToArray function.

  Of course this function allocates new memory whenever it converts an image, and as I convert 180 photos per second and shopuld program run for hours is quite a problem for me.

  The solution must of course be the free function (void * MyPointer). If I use malloc to allocate some random memory, instead of the imaqImageToArray, it works perfectly.

  However, when I call free() to free the memory allocated by the imaqImageToArray function, the LabView/dll-program crash.

  So I wonder what function the imaq functions allows you to allocate the memory and how I can get rid of him again. Is there another imaq-function?

  Thank you already!

  Greetings

  Sorry everyone for disturb you.

  I was just stupid... the answer is of course imaqDispose(void *object)

  Sorry again

  Thanks for the help

• Leak memory for the El Capitan mail

  Hello

  I installed el captain and discovered that using mail instantly crashes my computer.

  I took it to the apple store and they don't have any advice except wait for the fix to update operating software.

  I found some other threads about uninstalling 3rs advantage software mail, but that does not apply

  They mention also change some e-mail settings, but they don't work that my computer is frozen instantly if I run the mail application

  Any other advice?

  It is a broad topic, how could apple perhaps launched an operating system with this major fault, and why have they not all their team work to remedy immediately?

  I have my entire office tied up in this email, seriously apple job, he meets

• VMware Fusion 7 and VMware Tools - leak memory in Debian comments

  At some point during my updates from Mac OS X to Yosemite, VMware Fusion to 7.x and my Debian a guest to 8.0 "Jessie" on my 2012 Mackbook Pro, leaking memory of the Linux kernel is developed.  If I follow these steps, then I'd lose soon about 3 GB memory of the core area.

  1. Install Debian Jessie in a new machine virtual de VMware Fusion
  2. Install open-vm-tools or VMware Tools bundled.
  3. Perform an intensive IO as operation simply cat/dev/zero |-c 1000000000 head >/tmp/test.txt.
  4. Smem - wtk and see ~ 3 GB memory under the dynamics of the kernel memory, benefit.

  I opened the 15709682007 assistance request and the representative said that they will fix the problem in a future release. In the meantime, I have what seems to be a workaround for someone else that is affected.  Basically, pulling packages from backports jessie seems to have solved the problem.  This is based on the comments added to open-vm-tools.

  1. Add the Debian repository -backports jessie in /etc/apt/sources.list
  2. sudo apt - get update; sudo apt - get install t Jessie-backports open-vm-tools-dkms open-vm-Tools-Office
  3. sudo apt - get - t jessie-backports dist-upgrade (install kernel 4.1)
  4. Restart comments

  A few quick thoughts:

  1. If you have several virtual machines (or other programs) running on your computer host and VMware Fusion detects that there is memory pressure on your host computer, it uses the "balloon" (vmw_balloon for the latest distributions of Linux) Guest pilot to fly some memory of the guest OS.  This memory "stolen" would appear as memory Dynamics non-cache kernel inside the guest.  Running "sudo rmmod vmw_balloon" should release all memory climbed to the guest OS.  Note that using the balloon driver generally improves the performance of the guest and host, despite the appearance of fear "used memory" inside the guest-"used memory" is just a thing of accounting that we had to use in order to change the priority of the memory between the host and the guest.  It is not "used" in the conventional sense of the term.

  2. I believe that recent versions of virtual hardware non-cache dynamic kernel allocate the necessary memory for SVGA and 3D features (display RAM, texture RAM, etc.).  Disable graphic 3D acceleration or by reducing the amount of graphics shared memory if you are using a new version of virtual hardware (both in the VM > settings... > display) might help.  Decommissioning of a virtual equipment as early (in the VM > settings... > compatibility) can also help.

  See you soon,.

• Leaks memory in combobox, dropdown and listbox

  Hello

  Does anyone know if leaks memory in the combobox, dropdown and listbox widgets bugs have been fixed in CP 6? Or where can I find out the correction of bugs/problems?

  Thank you.

  Ago

  I just ran some tests and all three components seem to be safe from leaks memory.  Even if they had no memory leaks, Cp 6 now creates and destroys the slides that you see them giving you the best possible way to manage memory.  Basically, he cleans up after himself.  Kudos to the Adobe Captivate development team to resolve this!

• character OCR file causes the leak memory during OCR. Please can someone help?

  I'm trying to use the OCR to read characters from a LCD.

  All works :-) but... it leaks a LOT of memory, becoming unusable in a loop.

  I think the problem is the file of character. I tried several ways to create a (for example of the Interior vision assistant, starting in the stand-alone version of utility training - and without thresholding automatic), and none of them fix.

  The example of OCR OR vi works very well with its own abc file. But if I use one of my friends there is a leak memory every time that it runs, typically a few hundred k bytes.

  Please is - anyone can help or tell what is happening? Or fix the abc file?

  Thank you very much.

  Technical support to the United Kingdom have concocted with a fix. If they give permission, I'll post it here.

  The problem can affect any file OCR training using the GUI tools in 2013 release.

• Leak memory with Explorer.exe in the videos folder.

  Leak memory with Explorer.exe in the folder of videos with thumbnails enabled. Using the resource monitor, I can see that explorer.exe is playback of video files, while the memory gradually increases until it is 99%. No such problem with memory leak when I put the provision 'list' (i.e. without thumbnails). Disabling thumbnails also eliminates the problem of memory leak, but this isn't what I want.  Main videos folder is. MKV files, with the codec video within the container MKV h.264 high profile. I tried to dissociate all media files with Media Player Classic Home Cinema (which I use to watch mkv videos).

  More important, this problem seems only appeared after I installed SP1.

  Win7 x 64 Ultimate SP1, C2D E8500 8 GB of RAM, Western Digital 2 to Green Caviar.

  More info: I realized that this only happens with the video files that don't have any generated tile. It's like Windows Explorer is reading through the entire video file to generate a thumbnail, but even after awhile that yet, it does not generate a thumbnail.

  How to fix? Help! Thank you!

• leak memory in time real PDM

  Hi, this is Lee.

  I had the very serious problem.

  I'm currently building the real-time data recorder.

  But I found that there is a leak memory while I wrote the TDMS files.

  Let me explain further.

  Please watch for my project, I downloaded.

  There are target real time program. The title is "untitiled.vi".

  As you can see, I think that there is no accumulation of memory components...

  But if I don't have VI as 12 hours... it consume slightly patteren.

  Run Loganalizer.vi. or you can visit memory.jpg.

  I don't know why, but after he loses 17kBytes memory.

  Well... 17 KB of memory is not a big problem at the moment, but I intend to run this recorder as 2 months.

  This will eventually crash by memory loss.

  Thanks in advance.

  Hi Lee,.

  What do you mean by leaks memory, have you seen the increasment of memory when you run the VI without shutting it down? Or did you have seen memory leaks after you run the VI for 12 hours and STOP the race?

  If after a stop running, you see always 17 KB of memory "leak", what about you close the VI? Since it is possible that VI himself attributes may use of memory when running.
