where to check scheduled jobs in SunOS

Hi SunOS Experts

where will look up to correct the problem with my sunos, it normally shutdown on its own and reboot itself.
i am suspecting that somebody has scheduled it to be doing like that . which file can i look up to correct this problem.this is a server that is suppose to be up 24/7.
Thanks in anticipation for ur reply

processes are scheduled in crontab.

U can check that in crontab

check by using

crontab -l

it will give u the scheduled processes list.

crontab -l <user_name>

I think root only that can reboot server, it may be some thing panic.
you should try investigate log in /var/adm/messages.
