Solaris 2.6 "kernel panic"

[grega]

Not so much a question as a request for information. I have an Sparc Ultra-10 running Solaris 2.6. Over the past few weeks it has appeared to crash (overnight) for no apparent reason. Reboots worked fine.

I had "crashed" again at some point over the weekend so I tried to restart this morning. Just after volume mgmt started, I received a "kernel panic[cpu0]/thread error", then the system tried to sync the disks for about 1 hour, at which point I powered down for another attempt.

Before trying again I got on the phone to Sun and was speaking with an engineer when I tried another re-boot. This time all I got was a continous "RED State Exception" error on the screen.

Engineer said this was likely to be very serious and I'd probably need a new CPU or system board.

All well and good. So I'm just waiting for someone to come on-site for any repairs.

After speaking to the engineer, I again powered down and started up again. This time, everything is working OK. Fully back up into multi-user mode, no disk problems and all DB servers up and running.

"Very Strange" ... I think to myself!!

Has anyone experienced these problems before? Can this sort of problem appear to be intermittent.

Regards,

Greg.
