[Sunhelp] How can I get the reason for server unexpected rebo oting

[Kalusniak, Jeff]

Do a "file /var/crash/'hostname'/core" to see what process created the dump.

rebooting


Hello,

My server was down again unexpectedly this morning. And I get the following
info from /var/adm/messages:
panic[cpu3]/thread=2a1001dbd60
savecore: reboot after panic: zero

There is a core file under directory /var/crash/`hostname`;

Could anybody give me some hints on how to trace the problem ?

Thanks.
John

Did you run prtdiag -v?  There may be some info there.

With psrinfo, if you see that you have CPU's that are off-line, it may be
because the CPU failed.

grep for things like fatal or failed in /var/adm messages:

cat /var/adm/messages | egrep -v egrep | egrep -i
'panic|fatal|notice|savecore|core|error' >> file

This will get anything upper or lower case that match any of these words.
cat file to see if anything stands out.
