Hi,

We run here kernel 2.4.21-40.EL on kde environment.
However when the user start to work the X process take control of the cpu and after few days the X is stuck.


Please advice

How many users are we talking about here?
I'm not too familiar with the EL varieties, but you may know that X, and particularly KDE, are pretty heavy items -- they can be CPU intensive.
So, if any number of different users were logged in and using X/KDE sessions, the CPU would certainly become quite heavily loaded up. Compounding this might be un-closed sessions, unterminated processes or applications, etc.
Maybe, based on just the little bit of info you provided, a lighter desktop would be better in your situation, rather than KDE.

We talking on four hundred users working on independent desktop (same hardware).
The problem is that the Xfree log nor other log files indicated nothing.
After few weeks of work the X process take 80-90 percentages of the cpu, the X environment is stuck and not responding to any keyboard/mouse request.
Do you know how can I decrease the verbosity level of the log files ?
I'am suspected that the display card (nVidia Corporation NV41GL [Quadro FX 1400]-rev a2) causing that.

What kind of ligher X you recomnded ?


Thanks,


Amir
