Are you seeing a double fault panic?


We're seeing both.  At least one double (or more) fault finishing with
Fatal Trap 12: page fault while in kernel mode.  Subsequent panics have
been single fault (all visible on the IPMI console) Fatal Trap 9:
general protection fault while in kernel mode.

Could well be unrelated.  The system is undergoing hardware diags now.

Repeat this enough times and prison0.pr_uref reaches zero.
To reach zero even sooner just kill enough of non-jailed processes.


Interesting.  We've been getting kernel panics in -stable but with only
one jail started at boot without being restarted.

Are you using SAS drives by any chance?  Setting ethernet polling and HZ?
How about softupdates, gmirror, and/or anything in sysctl.conf?
