Greetings

I have a server that had a panic on CPU2 ... only once.

I set the diag-level to max and rebooted the box several times all normal. The only thing I have found changing was the vmstat. I am inclosing three outputs from that command. Would you mind having a look and seeing if there is any fault finding information that could be used as troubleshooting hits? Thanks in advance

Not sure if this is still relevant issue for you, but this is most likely hardware issue.

In general, good starting point for panic with $E is hardware side, CPU.
Also, any time you have EDP, data parity error, will be pointing at CPU as hardware issue.
Good side is that you have SPARC-II, old but solid. This $E panic is most likely to be ignored as it was one of those "cosmic ray" bit flips and system panicked. If it occurs again on same CPU in short time between last panic and new one, you should get CPU replaced.
