Help with Sun 3/160

[Brian Berndt]

Has anyone seen this problem?  We were not logged on to our Sun 3/160,
when we noticed it had rebooted itself.  Looking in the /var/adm/messages
file we found...

Nov 16 12:02:12 brazil vmunix: panic: vn_rele
Nov 16 12:02:12 brazil vmunix: syncing file systems... done
Nov 16 12:02:12 brazil vmunix: 
Nov 16 12:02:12 brazil vmunix: dumping to vp f0efeb4, offset 49258
Nov 16 12:02:12 brazil vmunix: 1022 total pages, dump succeeded
Nov 16 12:02:12 brazil vmunix: rebooting...

The reboot procedure returned no errors, so the system seems to be
functioning normally, but why did it reboot.  I have never heard of
"vn_rele" and can not find any reference to this error.  

This computer did this once before, about 2 weeks ago.  Then also, we had
no idea why the system would reboot itself!
