I remember a while back on an older specific version of BIND, that
there was a memory cache leakage bug in BIND specificly on FreeBSD
and no other OS; that I filed a ticket with ISC on.

They were able to identify it and fix it on the next version.

I'm running BIND 9.16 but still mostly back on FreeBSD 12.2.
