Check when the daily upload happens (If you have the pfSense Cron package, you can see this ) :

So for me, at 47 minutes past midnight.
You could change your cron timing ?!
Btw : example : as you can see, the cron services page lists a lot of timed processes.
If one of these has as a side effect that unbound gets restarts - and close at that moment the execacb starts, then for a short moment (a coiuple of seconds), DNS won't be working.
That would explain your issue.
You could see this : in the resolver logs, you'll see the stop and moments later the start of the resolver.
In the system log, around the same time, you see abc start, and fail ... and now you know why.
Again : this is just an example.
