22.1 Legacy Series / Re: Unbound restarting every 1 minute

« on: February 02, 2022, 08:07:15 pm »

I have traced the issue down to this log entry which repeats regularly.

2022-02-02T18:54:36   Error   opnsense   /usr/local/etc/rc.linkup: DEVD: Ethernet detached event for static opt2(igb2)

I have an Apple TV plugged into this interface. I have removed all static leases.

When the apple TV is in standby it causes the above issue. When on there is no problem.

22.1 Legacy Series / [SOLVED] Unbound restarting every 1 minute

[FIX]: Unplugged the Apple TV from ethernet and connected via wifi.

[EDIT]: Looks like the issue is an Apple TV that recently moved from WiFi to ethernet has two active leases in the DHCP table. Once it moved to ethernet I gave it a static lease which seems to have caused the issue. (This was not the issue)

2022-02-01T16:36:47   Error   dhcpd   uid lease 192.168.5.101 for client XX:XX:XX:XX:XX:XX is duplicate on 192.168.5.0/24   
2022-02-01T16:36:47   Error   dhcpd   from the dynamic address pool for 192.168.5.0/24   
2022-02-01T16:36:47   Error   dhcpd   Remove host declaration s_opt2_0 or remove 192.168.5.101   
2022-02-01T16:36:47   Error   dhcpd   Dynamic and static leases present for 192.168.5.101.

I'm not sure I understand why it has a dynamic and static lease given that the WiFi and ethernet have a different mac addresses and each interface is on a different subnet?

Looks to have solved the issue I will report back if not.


Hi All,

I recently did a fresh install of Opnsense 22. It's on a bare-metal i3 6100 with a 4 port intel nic and 3 realtek 2.5gb nics.

I had noticed issues with brief internet outages happening frequently and found that unbound was restarting every minute.

There don't appear to be any errors and I'm not sure what is going on. I do not have DHCP static mappings checked. I am using DNS over TLS using cloudflare servers.

Does anyone have any insight or how I might investigate this issue?

Thanks
Tom
