BIND Periodically Dying

[randomwalk]

Hello,

I'm using BIND to run DNSBL and it has been working great for a while.  But recently (and this coincides with upgrade to the most recent version of OpnSense), I find that BIND sometimes exits due to an error that I do not understand, and I'd have to manually restart it.  I've pasted the BIND log below (in reverse chron order).  Does anyone know why this is happening?

Is there a way to make BIND automatically restart upon exit?  Or at least get a notice that it died?

Thanks!

How often does this happen?

[randomwalk]

This never happened before when I was on 18.7.xx and I was running BIND to do DNSBL for many months.  Then over the weekend I got around to upgrading to the current 19.1.7(?) and this has happened maybe 2 to 3 times?  So maybe once every couple of days?

It's not super frequent, but because I run everything through DNSBL, the internet stops working when BIND dies.

I setup Monit last night to check on BIND and restart it whenever the process does not exist, but I can't tell if it's working correctly yet.

 Bind was updated to latest 914 from 912, maybe there is a Bug in Bind itself.
