• Memory usage increased on ESXi 4.1 for ESX 4.0

  Hi all

  Recently, we migrated about 130 virtual machines to a Cluster of U2 ESX 4.0 to esxi 4.1 u1 cluster and noticed that the memory usage is very high on the hosts compared to 4.0.

  The band u2 4.0 was 255GB of RAM between 9 guests and the new cluster has 355 GB of ram between 7 hosts.

  use of the memory of the 4.0 u2 was about 60-70% and now on 4.1, on the use of 90%. Can someone please explain this. It is more difficult to understand that there are 100GB more RAM available on the new cluster, but its use all this.

  ESX 4.0 host u2 were HP BL460 G1 - 32 GB each

  ESXi 4.1 u1 are HP BL460 G6 - 48 GB each.

  Thank you

  According to me, IT ' was all about GST (Transparent Page Sharing) and your new generation of CPU. This phenomenon is independent of the version of vmkernel. Let me explain briefly,

  New processor generation, such as Nehalem, have a feature called hardware support memory management unit, which includes a buffer cache called TLB (Translation Lookaside Buffer). I will not dive into the details but if vmkernel detects that your CPU have this kind of functionality, he decides to use pages (2 MB) memory instead of partial memory (4 KB) pages and also do not use GST as long as a restraint on resources of memory occurs. This is why you have a higher memory usage that you expect to see.

  To work around the problem (not a best practice but it is necessary), you can force vmkernel to work with small pages and trigger the GST. There is an advanced for this setting.

• Linked Clone - host memory usage

  Hello

  I have 2 separate infrastructure spacing to air both view currently running 4.0.1 with XP SP3 clients.

  Infrastructure 1

  • the host is HP DL380 G5 - 32 GB of RAM. (ESX 4.0 U1)

  • clones linked XP run at the host 400 MB average memory usage by linked clone

  Infrastructure 2

  • the hosts are 2 x HP DL380 G6 - 60 GB of RAM. (ESX 4.0 U1)

  • clones XP related work to the host 1035 MB average memory usage by linked clone

  These XP images are of the same generation, but on the more powerful G6 hosts, they run twice the host memory, which is make my ability to activate HA on this cluster.

  Does anyone know why these linked clones could be chewing so much more memory host? Half of them are not yet recorded.

  The cpu:s in the G6 is probably using "Main Pages", then the TPS will not take effect until the memory starts to be overcommited

  If this is the reason why there is no need to be worried, you can try to disable the support of large Pages by changing the following setting:

  Goto, dialog advanced settings, choose Mem. Mem.AllocGuestLargePage the value 0

• Relationship between memory of comments and the host memory usage

  Hello

  I noticed today that the memory usage of my cluster rose close to 90% in all of the blades. I checked and found that a number of virtual machines is everyone using over 3 GB of memory host. When I went in the performance monitor for each of these virtual machines, they used only a maximum of 400 MB.

  How the memory usage of comments relate to the host memory usage, and how I can reduce the amount of memory used host so I do not have a performance hit through the cluster?

  Running ESX 3.0.2, VC 2.0.2 Dell Poweredge servers with 2 processors 1.86 GHz quad core and 24 GB of RAM.

  See you soon

• Memory usage of Firefox flies away and crashes despite Reset etc.

  I use Windows Vista and recently, after he tried to update Java and Adobe plugins for Firefox browser last shot every time I use Firefox any open what really but especially if a video is open the memory usage keeps climbing and does not stop. Firefox crashes almost everytime. I tried the Reset, I tried to turn off and so on several plugins and others, and nothing has changed, but that the memory usage can climb higher and avoid crashing anymore. The fundamental problem of the memory usage crazy not stopped nor slowed down.

  It starts at an average use 200 k to 300 k, which was normal, except if he had run for hours or playback of videos for hours could go up to 800 k. For now, thirty minute walk with no video and four tabs is 1 300, 000 k. I don't know what does. I'll try to uninstall adobe and then use an earlier version but I have done so many things at this point, I'm curious to know who else has this problem. I have not tested the safemode, but despite everything I need a lot of these add-ons to what I use my browser for. I do not understand why the use of memory keeps climbing even when I do nothing. I run a system scan for virus etc, nothing. I know that I have an older video, its pilots updated card and I tried to turn on the option acceleration on and out also. Why Firefox would continue eating memory?

  The crash of the reports I receive look like this:
  BP-7cf4e751-66dB-49fc-8a05-083132130814
  BP-b680d967-eee5-44a7-a5e0-c1f422130814
  BP-5b457653-8B58-4ee0-80cc-32fe82130814
  BP-304b8b40-d4e5-4F36-AF10-de58e2130814

  Thanks to anyone who can help!

  Three of the four crash reports indicate a correlation with the Ghostery extension. The precise cause seems to be indeterminate. Can you make an exception for the video sites and see that allows, or try turning it off for 24 hours?

• Extremely high after upgrade to Firefox 12 memory usage

  After I've upgraded to Firefox 12, I started frequently affected by hot air balloon Firefox memory usage extremely high (2-3 GB after a few minutes of navigation) light. Sometimes it will fall back down to a more reasonable level (a few hundreds of MB), sometimes it crashes (probably trying to garbage collect everything), and sometimes it crashes. Usually the thread crash cannot be determined, but when it's possible, it's in the garbage collection code ( https://crash-stats.mozilla.com/repor.../list?signature=js%3A%3Agc%3A%3AMarkChildren%28JSTracer * %2 js C + % 3A % 3Atypes % 3A % 3ATypeObject * 29% ).

  I managed to capture a subject: report memory when Firefox had about 1.5 GB and have attached an image.

  A couple of things I've tried. I have a lot of tabs open (although don't load it the tabs until the selected option is enabled), so I copied my profile, all kept my extensions enabled, but all my tabs closed. I then left an open page http://news.google.com/ and it worked very well for several days, while my original profile goes down several times a day.

  I also tried to disable most of my extensions, leaving the following extensions that I refuse to sail without:

  Adblock more
  BetterPrivacy
  NoScript
  PasswordMaker
  Views
  Priv3

  However, the problem still happens in this case.

  Don't know if this helps or not. I'm looking forward to trying Firefox 13 when it comes out.

  Never knew what was causing the problem, but have disappeared since the upgrade to Firefox 13, accidents and memory pathological use.

• withdraw the authorization allowing you to monitor the memory usage

  I now often have either force quit, restart and started having panic 'of the core"since I agree allow Firefox CPU usage monitor. I'm still on OS X 10.6.8 on my Mac. I got no problem with anything since installing this OS X.

  However, from time to time with the latest Firefox 7.0.1 installation I think the program or my computer 'blocks' and seems unresponsive. I left active Firefox and resident on my computer last night and once again, everything will be inadmissible. I opened the monitor activity and noticed that Firefox was consuming 283 MB of real memory (now 298,6 MB) and I have this one open another tab for the Seattle Times. I withdraw my permission to allow Firefox to watch my memory usage and need to know how to delete the cookie or what ever that governs)

  Go to Firefox > Preferences > advanced > general tab and uncheck the box "send performance data" more information here.

• Message tells me that the memory usage has been 75%

  Hello

  I get (once a week) a message Bublé Tosh saying my memory usage average during the last 7 days was 75%.

• Memory usage

  We have a few GSM7228 and 5300 network (successful) on LAN switches. All switches has 90% or more of average use memory permanently.

  The network works fine, but we are curious to know the high memory usage. Average CPU usage is less than 10%, response time is great & packet loss is 0%.

  Any idea what could cause high memory usage? Thank you.

  Thanks for the reply. The version of the installed firmware is 10.0.0.53.

• Y50-70 display blinking rate increases exponentially on 40% memory usage

  I upgraded my new laptop of lenovo Y50-70 to win 10 about 1 month ago. Since that time I noticed that my screen would now and then Flash. I looked for a solution and I had a lenovo... Web site deactivation of 2applications in the Manager of tasks in safe mode. He helped abit because the flicker rate slowed, but it never disappeared.

  I investigated the system of som time now and I have found that when the memory usage goes up to about 40% flickering display rate increases exponentially. I have 8G of RAM, GTX 960 2 GB graphics card so I don't expect a problem when running my usually of programs. I won't even do games even if I know that the machine can handle but I guess it would be much worse if I tried.

  Please give me a permanent solution.

  Note from the admin; type of system added to the subject line

  I can't say for sure, but did you ask al updates to the Lenovo Web site for your system?

  You can download and apply all updates Win 10, including the latest version of the BIOS.

• creeping memory usage when you use NEITHER-9477

  Hi, I write output digital (4 outputs line, on request, 10 updates per second) in a loop using the DAQ assistant. When I use a NOR-9477 as the device output application use memory increases about 10 MB for 15 minutes and will eventually run out of memory.

  If I use a USB6009 as the output device, the memory usage is stable. Same code is used, the only difference is the physical channel.

  Any suggestions as to what might cause this behavior?

  

  Thanks for the tip Ravensfan.

  To distill the code down for the most part, one of the two VI is leaks memory - the NOR-9477 one. The other not...

  In any case, the solution to my problem is to convert the express VI DAQmx code.

• RT in LV 2012 Get memory usage

  Hello

  the VI 'Memory get RT Usage.vi' apparently is no longer available in LabView RT 2012. The help says to go to ni.com/info/f/ and enter a Code Info but this code leads nowhere. My question is now how to replace this VI with a pice LV 2012 in compliance of the code?

  Thanks for the help,

  Christoph

  The memory usage to RT has now been replaced by the function contained in the API of the System Configuration.  You can find the replacement feature in accessing public services RT > System Configuration > software RT > node system.  Drop this node in your code, click on it and go to the system resources.  There you should be able to find all the functions that were previously in the memory usage to RT vi.

• VI memory usage: very large data

  I'm working on the restructuring of an old project using structures that are more up-to-date. The old code used parallel loops to check if the values of the controls have been changed. My new code instead uses the event structures. Glancing on both memory usage statistics, I have reduced slightly before Panel and block diagram object memory, but I have more than 10 MB more 'Data' in the new code. I checked all my paintings and others, none of which is too large. Any ideas on what is using all this memory? Thank you!

  It is using new code from memory.

  

  And it's the former.

  

  Unfortunately, the code is too big to fix.

  How about a control or an indicator that has a large amount of data stored as default?  Who will eat the memory even if the indicator/control displays all these data at the moment.

  Close your VI and reopen it.  See if any of them contain data that you do not wait.  The data can appear even larger because the controls now contains data that is the display as well as the data that is stored by default as one of its properties.
