Data Panic BAD TRAP errors

One of our Sun E450 machines crashed and has this message in the /var/adm/messages after it rebooted automatically. An extract of the log is below. I suspect it is memory, but I am not sure. Can anyone give me any ideas how to diagnose this correctly?

Thanks
Margaret Floyd

I disagree. Usually (always?) when I've seen panics due to memory the messages point to which memory module is at fault. This output doesn't have any reference to a memory module or location.

I belive Bad Trap errors are due to a software bug, not hardware. In any case, if this server is under support you'll want to call Sun to enter a trouble ticket. If not, check google searching for the specific error info like "trap type 0x31" to see if you get any hits.
