Ed, can you take a look at this? It looks very like the problem appears after r332100. Also, Eugene or Vladislav, can you try revert r332100, rebuild/reinstall the world and try to reproduce the problem?

Confirmation from the original reporter or ae@ would be useful, ideally against the 12.2 BETA/RC images. Yeah, seems to be working from some point for me too, thanks. (In reply to Eugene M. Zheganin from comment #7) Thanks for the update. |
bsnmpd crashes right after start, was working on 11.x, regression happened after upgrade to 12.x. 100% reproducible, multiple instances: FreeBSD san01.bsh-ru.playkey.net 12.0-PRERELEASE FreeBSD 12.0-PRERELEASE r340754 GENERIC amd64 FreeBSD san01.boston.playkey.net 12.0-PRERELEASE FreeBSD 12.0-PRERELEASE r340673 GENERIC amd6 Backtrace: # gdb /usr/sbin/bsnmpd bsnmpd.core GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
