understand some log spamming (seems to be linked to FPS)

Hello

recently, my console (slog2info - w) journal seems to be spammed by the following recurring log message:

Anyone have any idea where we could be this log message of? Or what could be causing this spamming (several times per second)?

I think we all this kind of thing and just ignore it.

My technique for ignoring involves the use of 'grep' or 'sed' to filter unwanted lines.

Here's what I put in a script in my ~ folder after you add the path when I connect via SSH.

In ~/bin/slog, which is made executable with "chmod + x ~/bin/slog": (note that it is all on one line, no space between the [^.] and the (. *), just in case your browser wraps)

#!/bin/sh

slog2info -w | sed -re '/    default/d;s/^.{7}(\S+) ([^.]+\.[^.]+\.[^.]+)\.\S+\s+(\S+)\s+(.*)/\1 \2 \3 \4/'

With that, I just type "slog" every time I connect and get a 'clean' output that looks something like this, and which excludes all these lines with 'default' in them:

08:47:11.411 com.example.bb10samples 0 -----ONLINE-----

08:47:21.795 com.example.bb10samples qt-msg 0  SystemSoundPrivate::send: sound=8, msg="

The advantage is the lines are much shorter, a large part of the 'system' stuff, and I get always more than just the lines "qt - msg' in case I recorded other buffer slog2 names.

A simpler approach is simply to use "slog2info w | grep qt - msg' but I found this was not enough.

  • Some JPEG files seem to download very well, but are rendered incompletely.

    Some JPEG files seem to be well uploaded by Firefox, but they do not completely. A progressive JPEG will remain very rough and no progressive JPEG will be missing the lower part. Of all the things I tried, I think maybe it's a bug of rendering in Firefox. More precisely:

    • The images are downloaded properly. The page loading stalls not but join immediately. If I click with the right button on the image and click "View image", he appears completely. If I open the media dialogue information Page tab and look at the picture, it appears quite as well. More curiously, if I use the eyedropper color tool and hover where the rest of the image * should * be, it displays the actual image pixels in the raster and also returns the value of the color of the image in pixels, while the main browser window always makes these regions as being transparent. I added a snapshot of the species to this post. Therefore, the problem also doesn't seem to be a problem of CSS/layout of the page (the Page Inspector shows the img block correctly).
    • Clears all data cache and cookies, then by restarting Firefox in safe mode does not make a difference. I even installed a vanilla Firefox to a new virtual machine and had the same problem when opening these pages. Other browsers (tested: Opera, Chrome, IE) do not show the same problem.
    • Reload with forced renewal cache (Ctrl + Shift + R) most often does not change the rendering of the image, but will rarely showing either more or less incomplete than before.
    • I can see the issue going on with two images on two separate pages. I re-encoded them using different software and different settings, but the problem persists, then it doesn't seem to be a problem of corrupted images.
    • I created an example of a toy to try to reproduce the problem: a same page with a different image, created specifically to try to trigger the problem. What I've found, is that the issue is triggered when the JPEG file above a certain minimum size (somewhere between 15 and 40 KB). What seems to be the rendering of the image in the main window stops after the reading of the image up to a certain length. Once again, the image seems well to be loaded into the cache and memory completely as evidenced by the display when you use the view image, or information Page.

    I made three versions of the test page to try to reproduce the problem. Image of the first page is 11KO and always seems to go completely. Images of the second and third page are respectively 102 kB and 107 KB in size and will be usually incompletely. The image on page 2 use the progressive encoding, so the image will end up blurred. The image on page 3 use straight coding, so the image will eventually be rendered with the bottom part missing.

    So far, I'm not sure why only, I encountered this problem on a specific Web site pages. Something must be the trigger, but it doesn't seem to be a problem with the server, the page or images.

    Update: I introduced the site at Browsershots, asking for Firefox 35.0 renderings and a previous version for each of the Windows, Linux and Mac. Unfortunately, the renditions for Mac failed. As for the others, none of the versions pre-35, 0 present the display problem, and it is not present in Firefox on Ubuntu 12.04 LTS 35.0, but appears on Firefox on Windows 2008 R2 35.0.
    Here is the URL of the test pages where you want to check yourself: (darkened circles be transparent)

    http://www.abgase.org/firefox_debug.html (11kB, no problem)
    http://www.abgase.org/firefox_debug2.html (Progressive 102KO)
    http://www.abgase.org/firefox_debug3.html (no progressive 107KO)

    (Do Ctrl + Shift + R repeatedly if the question does not seem to show, to be sure. If by any chance I can get it to render properly, it will fail again after that 2-3 charging at the most.

    I did have a lot of time lately to make studying more. However, since the upgrade to Firefox 36 a few days ago, I can reproduce is no longer the question. This was confirmed during the audit on all my other Windows systems running Firefox: image rendering is usually interrupted when loading pages on Firefox 35.x, but still fine finishes after upgrade to Firefox 36.x.

    This problem can be considered resolved, that the bug seems to have been given to v35 only.

    I couldn't find anything relevant in the changelog of 36 of Firefox, but also found two Bugzilla reports that could have described the same problem, both claim that the problem goes away when you use v34 and/or v36:

    #1125789: image full size is only partially displayed
    #1126707: Firefox 35, MAC and PC image rendering problems

  • HAVE text images sometimes have some letters that seem "BOLD" or darker on the low ground, viewing

    Hello, we use HAVE to create product labels, and we noticed that images of AI are sometimes some letters that seem "BOLD" or more dark (i come).

    You can see the labels on our site of SPRAY of WATER MINERAL and benefits of mineral water spray | MINERAL water SPRAY

    Images of labels are a bit hard to see, but when when we write "spray of mineral water" i was more daring, told us Capturea.PNG when we have printed or displayed large scale image, it would correct itself.

    Anyone has any idea why?

  • Firefox is locked up and the problem seems to be linked to plug into the container. Is there any solution for this?

    Using Windows XP, a tab open in Firefox, selected an element on the Web page, loading icon appears and continuous, closed Firefox, tried to open Firefox, message that Firefox always on, closed firefox.exe by using the Task Manager, able to run Firefox again. This has happened a lot lately, and I don't remember what happens in previous versions of Firefox.

    Firefox use plugin - container.exe to run Flash and other plugins. The theory is that, if the plugin to crash, it would break all your tabs, any active plugins. You receive a message that crashed a plugin?

    If I understand the problem, Firefox hangs or freeze when trying to open a link, and you're leaving Firefox, after which it starts again until you kill firefox.exe in the Task Manager.

    Have you noticed any pattern to when Firefox freezes or crashes?

  • What ready NAS I need please? I don't understand some things.

    Hello

    I apologize in advance for asking below, which have probably been asked before--but not found by me.

    First of all, I currently have:

    * Ultra 2 with red 2x2TB WD

    * Pro 2 with 2x1To WD

    I now need 4 TB storage in a single machine. The HCL for readers of the above shows that the number of readers that are abandoned (Australia).

    I'm therefore looking for new OS6 models...

    * It seems to me that a Bay 4 logic - but if I used XRAID 2 with 4x2TB discs, would I 4TB? I saw messages where snapshots automatically adopt the available space. Can I use 4 x 3 or 4 TB drives?

    * I do not understand the differebce between the series 1, 2 and 3 4 models of the Bay. Are replaced 1 series?

    * Need is the EDA500 - or what is its role?

    * Can I save new OS6 models for my Ultra and Pro?

    Thanks for your help. I want to get a model that won't discontued "next week."

    Oh - backup Cloud is out of the question.

    Thank you very much

    Apple Mail only works when I restart in "safe" mode otherwise it becomes crazy, using all the CPU capacity without any correct output.  Seems to be connected with caches.  Any help?

    Generally, if your Mac works correctly in Mode safe, but not normally, then you have a third-party software that runs at the start of the origin of the problem.

    Safe mode disables most of the extensions of third-party startup and some Apple hardware, so it could be another problem for Apple, but I have never heard of your problem.
