Hi,

I had a named process aborting with an assert.=20

I have a full log of queries (it=E2=80=99s a recursive only server) and =
I haven=E2=80=99t seen anything unusual before the crash. Unfortunately =
the
program was stripped, I have recompiled it with debug symbols.

It is bind 9.16.6, built from ports on FreeBSD 11.3.

Any hint on what to look for? Fortunately I have another server running =
9.11. It wasn=E2=80=99t affected.

Thanks!





Borja.
