It looks like something has leaked a lock, resulting in deadlock.
The question is, however, which lock, and where. WITNESS may be able
to provide some insight into this; if you could run "show alllocks"
with WITNESS in place, that would be helpful also.
I add WITNESS and INVARIANTS to my config and the next freeze/boot
will have it [see PS].
This server is in production and running with a newer kernel for more
than 5 days now.
The diff (from apr 13) with the previous kernel [the one with the last
freeze] are:
Make sure you are also compiling in INVARIANT_SUPPORT and WITNESS_SKIPSPIN.
Sorry. I add this and kernel is builded now.
At the first boot I got a panic on a gif interface. I don't need it now so
I commented it out of rc.conf.local and reboot.
New kernel is running with WITNESS and INVARIANT... System seems not too loaded
...
I am at home and the serial console is not connected. I snapshot the KVM of the
panic
and attatch it to this mail for the record.
