Strange messages followed by a reboot.

[unixrocks]

Whilst messing about restoring a file from tape my server had a bit of panic and rebooted itself. Here are the entries in /var/adm/messages

Any ideas people???

Do you still have the top few lines of the panic, you have only given us the reg dumps which aren't going to be that useful....

 

[unixrocks]

here is the panic stuff. Only one line and not much use I think.

Looks like an internal kernel problem, the only references I can find to that system call are in papers like

http://www.usenix.org/event/usenix01/full_papers/bonwick/bonwick_html/.

I suggest you log a call with Sun about that one (if you have a support contract).

Possibly need this patch, if you're running 5.8 x86?
