Comment 3 for bug 2039952

This would explain a LOT of our deployment failures, especially when I run multiple deployments concurrently.

I checked our own server and:
$ grep "starting BIND" named.log*|awk '{print $1}'|sed "s/.*://"|sort|uniq -c
    853 19-Oct-2023
   1127 20-Oct-2023
   1386 21-Oct-2023
   1335 22-Oct-2023
    827 23-Oct-2023
    830 24-Oct-2023

We are currently on this version of the MAAS snap:
maas 3.4.0~rc1-14302-g.bb0dc28c1 30266 3.4/candidate canonical✓ -

But have been seeing this same behaviour (lost of DNS resolution under load) since at least 3.3.x, perhaps a touch older.

I'm adding a sosreport from our own server as well.
