During a newspaper production project, when we had more than ten

What sort of crashes? Application or system? Client or server? Finding
out why it crashed would be valued IMHO.
Here is my problem and some troubleshooting suggestions.

Subject: Re: [K12OSN] frequent crashes how to debug
We had a similar problem here and ended up being a bad motherboard (thank
goodness for warranty :o) ).
Anyway, a few things that might help if you are like us and do not have the
latest and greatest gadgets to test your system :o( :
First, you may want to check if the crashes happen everytime a "certain"
process (online backup?) or program runs/is started
Run the command dmesg, it will display a "sort of" summary of your log
file,
after the system has restarted and check for things failing to load,
conflicts, etc.
Boot your system with a "live" CD (Knoppix, etc) right after the crash -
some
systems are set to start a new log at every reboot - and mount the /var
partition to look for kernel panic/memory error messages in the
log/messages
file.
Boot the system with a system cd that has the memtest program (SuSe has it)
and test your RAM (long process). You can also download it here
http://www.memtest86.com/ .
For testing your processor and motherboard, you may want to put a heavy
load
on it. For example: here we compile Gcc and Qt at the same time and
watch for
swap usage, processor load, etc.
Good luck

I have frequent crashes using K12LTSP 4.2
When the server crashes two lights on the keyboard flash and the server
does nothing else. I have to manually turn off the server (ie hold on of
button for 5 secs) then turn it on again. Where can I look to try to find
out what is going wrong? Is there a log file I can look at?
I am using an AMD 2500XP cpu, 2 GB RAM @333, SATA 120 HD on Microstar
MS-KT6 Delta motherboard with GLAN.
I am running up to 11 LTSP clients and 3 windows machines that
authenticate
to K12ltsp and have home directories there.
We use firefox, Gcompris, Tuxpaint, open office, cross over office and
Scribus in roughly that order of use.
