As of the kernel crash dump? You can analyze them using "mdb".

In /var/crash/<hostname> you have multiple files all with a number as extention, just use the number as argument to mdb:

example:

# cd /var/crash

# ls

unix.0 vmcore.0

# mdb 0

A good command to "mdb" is then "$c" to see the stack trace.

The steps above, if you have any recent files in /var/crash/<hostname>, also you should check in /var/adm/messages* 7/M.

I got the following panic message after executing mdbvpanic(3, 101468b0, 1, b1fbe, 0, 0)what could be the problem?

Something like this?

panicsys(106d70c,71b1ff78,1434628,1,0,0) + 378

vpanic(106d70c,71b1ff78,0,0,0,0) + cc

panic(106d70c,106d670,2,2,0,0) + 1c

ptl1_panic_handler(71b1e590,0,72e58000,4024a148,72e58000,2000) + 68

If you do, try and run:

strings vmcore.<number> |grep MMU

if you see this message:

bad kernel MMU miss at TL 2

.. you are running into the same bug as i am :-) I haven't seen a fix for it, but i suspect that it helps if you add the latest recommended cluster or at least the kernel patches..
