Follow-up:
I found a couple of bsnmpd bugs that match this same condition: 
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195445
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203264

Both are closed as fixed (seemingly in FreeBSD 10.2). Since the problem persists in FreeBSD 11.0-CURRENT, I logged a new one:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=236408 

No Events found!
