Not related to your problem; "ST_DIV0" is a software trap as generated
by
"ta ST_DIV0" 

The typical cause of a "trap level 2, trap reason 0x2" panic seems to be
a kernel stack overflow.

You would need to have a stack trace to further analyze that.
(You can't allocate large chunks of data on kernel stacks)

It's seen especially when drivers are layered very deep and with
some 3rd party drivers (Vxfs in particular).
(I'm not sure if the stacks can be grown easily in 2.6)

Subject: How to know the trap reason ?


Admins,

My Enterprise 4500 (Solaris 2.6 105181-23) server panic with this panic
messge in its core dump message buffer :

 panic[cpu5]/thread=0x63ced4a0: kernel panic at trap level 2, trap
reason 0x2

in the /usr/include/sys/trap.h  this trap type is ST_DIVO ( #define
ST_DIVO  0x02).

I need to know the reason of the panic so how can I get some more info
about this trap type ST_DIVO ?

Any help would help.

Thanks
