By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Hi!

I'm not sure where the bug is exactly. I hope you can help me with this.

Originnaly I posted here, but got nothing:
https://answers.launchpad.net/ubuntu/+question/60151

Here's a copy:
---->
For a few months now, after a few hours of use I keep getting the "Maximum number of clients reached" xlib error message and cannot start any apps that would create a window. If I log off/log on (X restart) I can work for a few hours again...

Googling around I found some similar older problems but non of that helped.

I cannot bind the problem to running any specific program (I found some hints that firefox may cause this). It seems so that usage of the system is also not necessary, already happened that I just left the computer there and coming back after a 1-2 hours I already could not start anything.

I tried to check the number of clients with
xwininfo -root -children -tree
and
xwininfo -root -children -tree|wc -l
but it does not seem to be much worse compared to the state when the system works.

I use Intrepid/kde3 from http://ppa.launchpad.net/kb9vqf/ubuntu.

Please give me any hint, how to proceed! Thanks!
---->

I still cannot find any program which causes this, but it definitely happens only with this kde3 build. I installed xfce and when I'm starting an xfce session I never run into this.
So, I hope maybe you can give me a hint, or tell me where should I start searching.

Thanks!

This is an odd problem!  I have been running KDE3 continuously on several Intrepid servers with uptime measured in months, not hours.

Can you give some more details about your hardware?  I wonder if this is a graphics driver/Xorg issue.  Remember when KDE4 first came out and highlighted an obscure problem with nVidia graphics drivers?  It is possible that KDE3 is exercising a little used, but broken, part of your graphics driver.
Comment 2 dzsabor 2009-02-17 14:58:28 CST 
It is possible then that my graphics driver causes the problem. I've an nvidia GF FX 5600 and I was recently forced to change to the legacy driver (currently 173.14.15) as the latest drivers do not support this card anymore and the newest driver that still supports it does not complie with the new kernels.

Though I think this error also occured with the x.org nv driver, I've to check it again to make sure.

Is there a way to workaround this?

This does not appear to be a bug within Trinity itself; closing as INVALID.

If the problem persists on the latest versions of Ubuntu please reopen this bug with that information.
