Hi guys,

I have a Solaris 10 server that got rebooted...Vmcore file created..I am a newbie in this filed, but I tried to analyze the cause of reboot anyway. I used 2 tools to analyze the crash dump and got to 2 different conclusions, so I need help to clarify the real issue.

Using mdb, looks like the panic was created by an Oracle-RAC related process (oprocd.bin):
             cpu                1
          thread      30004243500
         message forced crash dump initiated at user request
          tstate       4400001605

              g5         88000000
              g6                0

Don't ask me how I ran te above commands, just used a similar info from web :)

Using SCAT, looks like the crash was forced from keyboard (STOP+A):
CAT(vmcore.2/10U)> analyze

core file:      /var/crash/xxxxxx/vmcore.2
user:           Super-User (root:0)
release:        5.10 (64-bit)

hostid:         xxxxx
dump_conflags:  0x10000 (DUMP_KERNEL) on /dev/dsk/c1t0d0s1(3.90G)
time of crash:  Wed Jan 30 01:06:32 MST 2013
age of system:  57 days 13 hours 34 minutes 22.61 seconds
panic CPU:      1 (2 CPUs, 8G memory, 1 nodes)
panic string:   forced crash dump initiated at user request

==== system appears to have been Stop-A'ed ====
Of course, the output is longer; if relevant I'll paste here...

Now, which source should I trust?

Thank you!
