Hi, I'm running opnsense 26.7.1_1 as guest on proxmox
Since enabling Unbound DNS in Reporting I've noticed that the device is making a large number of A and AAAA DNS queries against itself (ie. the source is localhost) for whatever mirror is configured in System->Firmware->Mirror
At first I notice that www.mirrorservice.org was no. 1 in the top ten passed domains. When I changed this back to the default it was soon replaced with pkg.opnsense.org
Examining the Reporting->Unbound->Details I see that the device is querying whichever source is configured on average 5 times a second, with ~200k queries for the two mirrors I've had configured in the last 24hrs. The behaviour doesn't change if I select a different firmware mirror.
Example logging:

This doesn't seem right to me. Is this expected behaviour? It feels like some script to check for updates is stuck in a loop.
