Hi All,

I have a few time the server panic and auto-rebooted with crash dump. I am
looking at this post
http://wiki.illumos.org/display/illumos/How+To+Report+Problems but it seem
the info is not updated.

When I run this:
echo '::panicinfo\n::cpuinfo -v\n::threadlist -v
10\n::msgbuf\n*panic_thread::findstack -v\n::stacks' | mdb 5 > ~/crash.5

root at sgbk02:/var/crash/unknown# echo '::panicinfo\n::cpuinfo
-v\n::threadlist -v 10\n::msgbuf\n*panic_thread::findstack -v\n::stacks' |
mdb 5 > crash.5
mdb: warning: dump is from SunOS 5.11 omnios-8c08411; dcmds and macros may
not match kernel implementation
mdb: failed to read .symtab header for 'unix', id=0: no mapping for address
mdb: failed to read .symtab header for 'genunix', id=1: no mapping for

mdb: invalid command '::threadlist': unknown dcmd name
mdb: invalid command '::msgbuf': unknown dcmd name
mdb: invalid command '::findstack': unknown dcmd name
mdb: invalid command '::stacks': unknown dcmd name

Can someone update the wiki on how to get the kernel messages and stack
information?

Thanks & Regards,
Lawrence.
