accroread causing ld-linux.so.2 to be stuck using 50% cpu

Well that fix is you can not view the pdf directly in firefox but in the standalone acrobat that can be launched with open from firefox. I do not see this as a big problem for me if it works.

I uninstalled that a few months ago when these problems started. The viewing as html worked for me like 1 out of 5 times so I mostly clicked Open which activated the accrobat plugin ...

Hello,

glad to have found this thread. I have not seen this problem with the acrobat nsplugin (because I don't use it), but I have seen it with the
acrobat reader (not started from browser)
and
matlab !!!

Actually when I run matlab ld.linux.so.2 eats all my RAM very quickly. Now I have not updated matlab in about 6 months, and the problem started only very recently.

Hi,

this is strange. From time to time I have a process called ld-linux.so.2 which needs uses all of my computers RAM (2GB). This is probably somehow caused by my cron daemon as /var/log/messages says it started some minutes before. But there are some strange points:

the process is owned by my local user and not root. My local user does not have any cron jobs.
the root's cron job is just the one that starts the things in /etc/cron.* and they are makewhatis, prelink, logrotate.cron. I can execute everyone of them as root without any problem.

Any idea? It's probably prelink but how can I reproduce the error?

Cheers

I get the same error while opening pdfs in opera with acroread.

It doesn't happen every time but it uses up a lot of ram and my load goes up to 50%.

If I save the pdfs before viewing them this error doesn't come up.

Although for me I do not get high memory usage I do get high cpu usage.

For the record, the problem still exists. I also have an x86_64 system and a 32-bit browser plugin with ndiswrapper

Out of curiosity, is there a way to tell the system that when a process named acroread together with it's descendants consumes more than a certain amount of resources it should be killed? I could probably write a littlle cron entry to do something like that, but is there anything "more official"?

I've had the same cpu/mem usage problem for months with both Firefox 2 and 3 + acroread. I can kill the ld-linux.so.2 process just by "kill <pid>" and then the problem is gone, but acroread won't load files within the browser until Firefox is restarted.

On the adobe blog, they suggest using a package called "lsb" for debian-based distros, which I think is our "sys-apps/lsb-release" but it's masked in portage right now for amd64.

There's nothing like lsb packages in portage since it's, roughly, just a way of sorting and naming the files. By simply making a symlink of /lib32/ld-linux.so.2 as /lib/ld-lsb.so.3, you can observe that acroread starts without attempting to exec ld-linux.so.2 anymore. This however doesn't solve the problem, it just shows a bit more that acroread is leaking memory.
Also with firefox 3 it seems each pdf is opened with a new instance of acroread, so when one of them hangs it's not necessary to reload each tab containing a pdf before it works again.
Finally the best way is to get rid of the nppdf.so link to avoid firefox use the acrobat plugin.
