Good.
Since installing the server, we've two times experienced that the server
completely hang: all processes became unresponsive and there was no longer
generated any log information.
It sometimes works out that you might still be able to ssh in from a
remote machine and get some logs/dmesg, run top.
On a Dell Poweredge 750 {and I think other models see Dell forums} with
FC3, if runlevel 5 was used or started, then an X process would go
99-10%, making the machine severely slow. {It required a reboot to get
around this condition}. Just a thought.

You might also be able to leave some xterms open running top and tail -f
/var/log/messages to see if anything is being logged.
Another thing to try would be a serial console, since any emissions
before death would then be easily captured. Boot with
console=ttyS0,9600n1 or some such and fire up minicom on another machine
and use a null {crossover} serial cable.
Good luck.
