[T2000] Solaris 10 freezing [how to debug ?]

Hi all,

We are using a Sun T2000 (Solaris 10) machine for our Veritas Netbackup master.

At least twice a week we are coming in in the morning and the machine is in a
frozen state. I log onto the ALOM and cannot even switch to 'console'. The only
way to recover is to send a 'break' and 'reset' from ALOM.

This is a seriously important production server, can anyone suggest how I can
debug why this is happening ? Dtrace ? mdb ?
