Sun 3/160 reboot - automatically?

[Brian Berndt]

Just now my Sun rebooted!  I was logged in and running sunview, but not
typing anything at the time.  A few other users were logged in, but I
don't think they were doing anything unusual ( telnet to an IBM 3090,
reading News, etc. ).  I was talking to a sales rep and turned to look at
the console, when I noticed the machine rebooting! ?  The log in
/var/sdm/messages follows: 

Nov  2 11:24:12 brazil vmunix: panic: vn_rele
Nov  2 11:24:12 brazil vmunix: syncing file systems... done
Nov  2 11:24:12 brazil vmunix: 
Nov  2 11:24:12 brazil vmunix: dumping to vp f0efeb4, offset 49258
Nov  2 11:24:12 brazil vmunix: 1022 total pages, dump succeeded
Nov  2 11:24:12 brazil vmunix: rebooting...

Has anyone heard of this before?
