unbound signal 11 on pfsense 21.02-RELEASE (amd64)

[mxw39]

unbound crashes periodically on 21.02 with signal 11. I can't find other logs to troubleshoot what is causing unbound to crash.

You'll find the logs below. Around the signal 11 entry I've seen suricata rotating logs. But turning off suricata does NOT resolve the crashes.

Are you experiencing similar issues with unbound on 21.02? Any pointers to debug the issue is appreciated.

There is a long thread in the Development sub-forum discussing this issue. The pfSense team is trying to reliably reproduce the issue.
