Adobe Reader CPU Usage

Dec 21, 2006 8:16 AM

Hello All,

The problem i'm having is that "acroread" process after being open for some time (many hours or even days) starts to use all the CPU without anyone touch the application. This causes lots of trouble because i'm using all the time simulation software and "acroread" starts to share CPU with my mission critical applications and I cannot be always checking if acroread has crashed.

I've tried with more than one Linux distribution and have read in some web forums that other linux distributions have the same problem.

Currently i'm using CentOS 4.4 (Linux 2.6.9-34.0.2.ELsmp #1 SMP Fri Jul 7 19:52:49 CDT 2006 i686 i686 i386 GNU/Linux)
Even in CentOS 4.3 , 4.2 , 3.4 they all had the same problem.

I'm using acroread 7.0.8 but older versions of 7.x did the same.

Please share some ideas about this issue.
Thanks

    Hi Hugo,

    This is a known issue and we will be working on this for the next release.

    Thanks,

    This still occurs in Reader 7.0.9. Did the above fix make it into this version?

    The specific issue I seem to have is that opening a PDF from within Firefox and then closing the browser tab leaves acroread running in the background. This process will eventually consume 100% of the CPU.

    The fix did not make it into Reader 7.0.9 It shall be available in the 8.x version.

    The cpu utilization has been killing us, so we came up with a temporary band-aid to hold us over until version 8 comes out. Just run this command every minute or so via crontab, and if there are any acroread jobs using 80%+ cpu that have used a full minute of processing time, it will kill it.

    kill `top -b -n1 | grep acroread | awk '{ print $1 " " $9 " " $11 }' | egrep "(1[0-9][0-9]|[8-9][0-9]) [0-9]*[1-9]:" | awk '{ print $1 }'` 2>/dev/null

    It's definitely not pretty, but it does work. I'd be interested to see if anyone else has found any creative workarounds for this issue...

    Hi Toby,

    The pre-release of 8.x version is now available, which has the fix. I would suggest you to try that out and confirm to us. Your input is valuable to us.

    If you are interested to be part of the 8.x pre-release program, please post your email address. I would get you enrolled.

    Thanks,
    Anupam Garg

    Hi,

    Is it still possible to try the 8.x pre-release for Linux ?
    As I am seeing the CPU problem often every day, I would be happy to test this new version and provide feedback.

    Thanks,

    Rui

    Hi Hugo,

    Could you please let us know in what state you left Adobe Reader opened in the background?
    1 - Did you have one or more documents opened?
    2 - Was the Adobe Reader window in minimized (iconified) state?

    That will help us identify the causes of high CPU usage even when idle.

    Thanks,
    Gaurav

    Hello,

    Essentially every time we use acrobat reader version 8.1.2_SU1 we have the problem of 100% cpu usage as described in earlier messages. This is very undesirable, can you please fix it? Do you need any further information for debugging. Information about a host on which the problem is experienced is below.

    % uname -a
    Linux usplmwd500342 2.6.18-92.1.10.el5 #1 SMP Wed Jul 23 03:56:11 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux

    % cat /etc/redhat-release
    Red Hat Enterprise Linux Client release 5.2 (Tikanga)

    % acroread -v
    8.1.2_SU1

    Thanks,
    Peter

    Same problem with 100% CPU usage when using the acroread as browser plugin.

    The first opening of an PDF is ok. After few minutes (even if the PDF has been closed, that means, an other web page is opened) the acroread process flips to 100% cpu usage and every further click on PDFs is significant slower.

    openSUSE 10.2 (X86-64)
    Linux virto 2.6.18.8-0.10-xen #1 SMP Wed Jun 4 15:46:34 UTC 2008 x86_64 x86_64 x86_64 GNU/Linux
    acroread-8.1.2_SU1-0.1
    seamonkey-1.1.12-1.1

    The home directories are mounted via nfs and automounter.

    We have about 50 users, which are regulary complaining about the bad performance of opening and printing PDFs some few minutes after opening the first PDF with acroread plugin in the browser.

    I have the same problem with acroread-8.1.2_SU1-0.1, openSUSE 10.3 (Opteron 175). Firefox 3.03.

    The problem can be recreated very easily. I just need to open any pdf file on the web. I can then run the top command and within a few minutes the acroread process will be up to around 50% CPU. If I leave the process then it will soon become 100%. The acroread process keeps on going even after I closed firefox.

    Dear Mr. McGeoghan,

    Could you please give us the steps of reproducing this condition, were you running Reader standalone or trying to open a PDF inside a browser (which browser also would be a great input)

    Thanks

    Attached file is using 100% cpu on 64 bit Jaunty.

     

    Steps to reproduce.

    1) Open attached pdf in adobe reader.

    2) There wont be cpu usage initially.

    3) Wait for 5 min to see the surge in cpu usage.

     

    system info:

    Linux hercules-linux 2.6.28-14-generic #46-Ubuntu SMP Wed Jul 8 07:41:18 UTC 2009 x86_64 GNU/Linux

     

    Acrobat reader info:

     

    acroread:
      Installed: 9.1.2-3jaunty1
      Candidate: 9.1.2-3jaunty1
      Version table:
    *** 9.1.2-3jaunty1 0
            100 /var/lib/dpkg/status

    Not sure whether this is the same problem or a different one.
    For us acroread consumes all the memory and the CPU is maxed out swapping
    until the oom manager kills acroread and the machine recov

     

    Our machines are 2GB RAM with 2GB swap, running the x86_64 version of
    Scientific Linux 5.3 (a recompilation of Red Hat Enterprise Linux 5.3)
    - we don't really need a 64bit OS but some local apps run faster in 64 bit.

     

    We first saw this with, I think, acroread 8.1.4 and continues through to 8.1.6.
    (I am reluctant to switch to v9 since we are using it as a pdf viewer
    not a flash viewer - adding javascript was bad enough - we would be
    more likely to move to evince or another open source pdf viewer).

     

    Typically acroread chews memory for users who run firefox 32bit
    and the nppdf.so Adobe plugin, but I cannot confirm that it never
    happens for users whose firefox opens a separate acroread process.

     

    What extra imformation would help to debug this ?

     

    Thanks,

    Hi,

     

    The high CPU usage problem when acroread is used inside browser on 64-bit systems has been fixed in AR 9.x. You could download the latest Adobe Reader 9.1.3 Security Update directly using the FTP link, or use YUM to install the update. Please use it and let us know if you still see 100% CPU usage.

     

    Thanks!

    Sincerely,

    Sanika

    Dear Sanika,

     

    The nppdf.so shared library that is provided in the download for linux is an ELF32 object, so is completely unusable with 64-bit browsers.

     

    If you can make a 64-bit build available, I would be happy to try it out and report back on how well it performs.

     

    Regards,

    Peter.

    Sorry - forget I wrote that. I've just figured out now to use nspluginwrapper.

     

    I'll see how the plugin behaves. Initial indications are good: it loads very fast.

     

    Regards,.

    Peter.

    It would be nice if you can take a look to the problem that I´ve reported in this post:

    Problem persists in Adobe Reader 9.4 in CentOS 4.8. Running the stand-alone executable without even loading a PDF, the process immediately consumes nearly 100% of core.
