Description Alan Amesbury 2013-06-27 02:00:00 UTC 
Starting bsnmpd on this system triggers a panic.  The hardware is thought to
be OK, but dedicated testing of RAM, etc., isn't possible at the moment.
I've captured two backtraces and, to my admittedly novice eye, they appear
identical.  Output to follow shortly.

How-To-Repeat: Starting bsnmpd reliably triggers this panic.
Comment 1 Alan Amesbury 2013-06-27 02:07:57 UTC 
Two example console output and crash dumps are attached.  The first is
what happens when bsnmpd is enabled and the system is allowed to boot.
The second is the result of starting bsnmpd after the system had been up
for a while (about 30 minutes).

The kernel config is derived from GENERIC and is attached
(OITSEC-9.text).  A copy of /var/run/dmesg.boot is also attached
(dmesg_boot.text).

Please let me know if additional diagnostic information is needed.

Is this problem reproducible with any of recent FreeBSD versions, e.g. 10.x or 11?
Comment 4 Eugene Grosbein freebsd_committer freebsd_triage 2017-06-27 17:33:02 UTC 
Feedback timeout. Please try any supported version if you still have this problem.
