Hi,

I had a system crash on one machine and would like to analyze the crash
dump. So I installed SUNWscat4.1_Lite. But it crashes immediately:

# ./scat /var/crash/anduril/unix.0 /var/crash/anduril/vmcore.0

Has anybody seen this? Is there a workaround?

BTW: the crash looks like this:

TIA,

Solaris CAT 4.1 was released well before Solaris 10. As such it can't be
used to look at Solaris 10 crashdumps.

You'll need 4.2, which is currently going through the release processes
and hopefully shouldn't be too long (but I wouldn't hold my breath).
