Unbound Restarting every 2 hours after upgrade to 22.7

[andrema2]

Hi

I have seen at Unbound log that it has restarted itself 3 times since 9am today exactly every 2 hours.

I didn't see any other information on the log that could explain it. Any one else having this issue ?

Same here, except it seems to be every 45 minutes, see attachment. I increased verbosity, maybe something comes up.

[jclendineng]

Every 20 minutes here, fun times :)

[dinguz]

Does it perhaps restart at dhcp renewal of one the network interfaces?

[chtse53]

Mine frequently renews the wan ip address, which didn't change, and caused unbound to restart.

Level 5 logs just show <code>got control cmd quit</code> for every thread, so not much more info there.

I have checked my logs, and indeed unbound is restarted upon dhcp renewal. Wouldn't it make sense to make it a bit smarter and only restart when the ip address changes?

[andrema2]

Yeah, this is not how it was working before. I upgraded to 22.7_4 and the behaviour is the same. Apparently there is something wrong with the current implementation.

Might be a side effect of https://github.com/opnsense/core/issues/5624

Need to check on Monday.

I need one info from everyone having this issue: under WAN settings, what is your IPv4 type?


Cheers,
Franco

I need one info from everyone having this issue: under WAN settings, what is your IPv4 type?

IPv4 Configuration Type: DHCP

[dinguz]

I have a fiber setup with internet access on one vlan (a PPPoE connection which uses dhcp) and I have IP TV on another vlan which also uses dhcp, but directly, without PPPoE.
Please let me know if you need more specific info.

[joysense]

Same issue. Noticed some tcp errors since I was using DoT. Had switch over to dnsmasq in mean time

[miroco]

In my case Unbound restart with a 30 min intervall. Wan uses DHCP on IPv4.

[franco]

Has anyone checked their IPv4 lease time? It might "coincide" with the reload interval measured.


Cheers,
Franco

[miroco]

It does coincide
