I'm not sure if this is related to the OPNsense 26.7.x update, but it seems to have started then - After an OPNsense reboot, Unbound starts and runs successfully for about a minute. Then it crashes and I have to manually restart the service to bring it back up. What could be causing this? Is this a 26.7.x bug?

What does Unbound log?

Thank you for sharing this. I actually forgot that I saw that already and chimed in!

This is what ChatGPT helped me come up with. This was in order to submit an issue, which I have not done yet. I figured I would try the forum first.
QuoteRelevant log output
During boot, multiple interface events invoke unbound_configure_do():
2026-08-28T10:48:41-04:00
/usr/local/etc/rc.linkup:
plugins_configure dns (execute task : unbound_configure_do())
2026-08-28T10:49:15-04:00
/usr/local/etc/rc.linkup:
plugins_configure dns (execute task : unbound_configure_do())

/usr/local/etc/rc.linkup:

2026-08-28T10:49:36-04:00
/usr/local/etc/rc.linkup:
plugins_configure dns (execute task : unbound_configure_do())
At approximately the same time, the Unbound log shows:
2026-08-28T10:49:35-04:00
info: start of service (unbound 1.26.0)
2026-08-28T10:49:36-04:00
info: service stopped (unbound 1.26.0)
2026-08-28T10:49:40-04:00
info: start of service (unbound 1.26.0)
The interface events immediately preceding this include:
2026-08-28T10:48:41-04:00
kernel
vlan0.30: link state changed to UP
2026-08-28T10:48:41-04:00
kernel
vlan0.40: link state changed to UP
2026-08-28T10:48:41-04:00
kernel
vlan0.10: link state changed to UP
2026-08-28T10:48:41-04:00
kernel
vlan0.20: link state changed to UP
There are also repeated IPv6 initialization messages during boot:
dhcp6c: Sending Solicit on igc0
and:
radvd_configure_do(auto) found no suitable IPv6 address on lan(ixl1)
radvd: sendmsg: Can't assign requested address
At present, the WAN and LAN interfaces have only IPv6 link-local addresses and no global/delegated IPv6 prefix.
There are also repeated kernel messages:
pfr_update_stats: assertion failed.
I do not know whether these are related.
