Ricardo,
First thing I'd look at is memory. With 10 clients running KDE, you are definately pushing the machine.
I'd grab memtest86 and run it for a while, and see if you find any problems with the ram. You can put memtest86 in the grub.conf, and
run it at boot time.

Hello
I have a Debian server running LTSP 4.1, with KDE 3.2.1. About 10 machines are connected to it through switches (some 10MBs, other 100MBs). Machines vary from Pentium1 to Duron. Randomly, the server will lockup completely and I have to hard reset it. We are lucky if it only locks once a day, but there are days that it will lock two or three times.
What I have tried: different kernels (2.4 and 2.6). Different distributions (Conectiva, Knoppix) with different KDE's (3.1 vs 3.2). Completely different server hardware. Nothing made a difference. Users only use Mozilla (1.7.2) and OpenOffice (1.1.2).
Also, nothing is recorded in the logs. In /var/log/messages, at the point where the server locked, there appears only a bunch of "@@@@". Before locking, there is nothing of interest in the logs, everything seems to be working fine. No pattern may be observed also (i.e. locks happens after something appear at the log).
After hard resetting, everything goes back to normal. Except, of course, when the filesystem gets corrupted (the kickerrc, a KDE configuration file, is quite sensitive BTW).
So, a few questions:
1) What could make a server lock that badly?
2) Can problems in some client cause this? If yes, could it be too old hardware (network card, maybe)?
3) Could it be some network problem (switches, cables)? Maybe some strange packet that makes the server lock?
Any other insight would be nice.
Thanks!
Ricardo.
