How to Troubleshoot HP UX 11.23

[severity]

Hi,

I'm a newbie and I have a problem with my system, which I hope anyone would
guide me through it or point me to any resources to at least identify
it.
I am administrating HP L-1000, using os hp ux 11.23 with 2048 mb RAM

and for the last few days it suddenly reboot for about 4-5 times

i'tried to check the system log but i don't know where to start and ended check it randomly, so plz guide me how to identify the problem

thx

What are the last entries in syslog.log?

Any entries in the shutdown log?  /etc/shutdownlog

Any panic dumps in /var/adm/crash/?

Have you gone to the GSP/MP to look for errors there?
