I’m using Fedora 7 with Acroread 8.1.3. Without setting the proxy, Acroread would utilize 100% of the CPU… which is what lead me to this web page. I am behind a corporate firewall and proxy, so once I manually set the proxy and restarted Acroread, my processor utilization was back to normal. Thanks!

The system is still Debian “lenny” on AMD Turion X2 notebook, linux-kernel 2.6.28.

I installed the compiz, and after I started it, the 100% CPU utilization problem came back!

After I uninstalled compiz, the problem disappeared again!

I also had this problem, but now it seems to get solved :-)

My config:
Amd turion x2 notebook (fujitsu-siemens).
OS: Debian testing release (lenny), 32 bit.
I installed the reader from the deb package.

Im not sure, that it was the thing that solved, but after the kernel upgrade from 2.6.26-1 to 2.6.28 I installed the reader again, and now it works well as standalone, and also in iceweasel/firefox (i had to compile the kernel from source).

There was also another change in the environment, I installed the latest official Nvidia Geforce driver on my notebook. Before that I was using the free driver shipped with Debian.

I hope this helps You too!
Bye!

What to say else that I’m not impressed by adobe developpers…
A simple googling shows that everybody seem to have the bug, except adobe: “unfortunately we are unable to replicate this issue locally”

The problem happens if you open a pdf from inside firefox. When you close the tab with the pdf in it the cpu will spike.

I tried this with Opera instead of firefox and the problem does not happen

Sounds like a memory leak in the application.

Even on Fedora 9 and Centos 5.2 (core2duo, 2,4MHz, 3GB RAM). I cannot understand why Adobe is not able to solve this problem. Have a look at the output of “top” (rearranged for the forum):

In the Windows version you can disable the auto-update feature, but I can’t find the same option in the Linux version. Am I missing this or it is not there?

Thanks,
Tuatha

acroread-8.1.2_SU1-0.1
firefox 3.0.1-2.1
xorg-x11-7.2-135.5

yeah this is getting really annoying. I don’t see this happen if I view the pdf with regular adobe acrobat reader (only happens when I view in firefox).

It doesn’t always happen immediately (but can).

If I close the web page (window or tab) it doesn’t end the ‘acroread’ PID). I have to kill it. Sometimes it won’t start “hogging” the CPU for a few hours after the process has been running, or even after the window/browser has been closed.
