In Irix,
crashdump reports are stored in /var/adm/crash

Also, (reading from the man page) if it is configured,
a compressed coredump will be copied from /dev/swap to 
this area when the system reboots.
There is a space limit set, so it won't write if there is
less than 'minfree' on that disk.

On reboot, the system writes what, IMHO, is a rather nice
and useful analysis of the crash, in a file called 'analysis.n'
This has the reasons for the crash etc.

"In the event of a software-detectable system crash, one of the last
steps
     that the kernel performs before shutting down is to write the
contents of
     system memory to the dump device.  There are several ways in which
this
     information can be used to determine the cause and solution to the
crash."
