Hi,
I'm seeing the same thing on Hyper-V, though less frequently than described here.
Environment:
OPNsense 26.7.6-amd64, FreeBSD 15.1-RELEASE-p4, OpenSSL 3.5.9
Virtualized on Hyper-V (host CPU: AMD EPYC 4584PX), VM with 8 GB RAM
Unbound 1.26.1 (since 18/09), Python module with dnsbl_module loaded
[Upgraded to 26.7.6 on: ...]
What I observe:
Today, 2026-10-09 04:15:53, kernel log:
pid 19272 (unbound), jid 0, uid 59: exited on signal 11 (no core dump - denied by kern.coredump)
The VM had rebooted at about 04:10 and Unbound started cleanly at 04:10:55. It crashed roughly 5 minutes later.
The resolver log shows nothing unusual before the crash. The last line is dnsbl_module: successfully opened pipe at 04:11:05, then silence until "Closing logger".
Earlier unclean death on 2026-10-04 at 03:01:31: the resolver log shows "Closing logger" without the usual "service stopped", and no restart afterwards. Unbound was apparently down until I rebooted on 2026-10-09 01:16, so about 5 days without DNS resolution from OPNsense. I can't confirm a signal 11 for that one, since my kernel log excerpt has no matching entry.
I restarted Unbound manually after noticing it was stopped on the dashboard.
I have not downgraded the kernel yet. Reverting to 26.7.5...
Thanks
