Hi,

I had a named process aborting with an assert. 

<26>1 2020-08-27T15:52:04.000000+00:00 host named 6520 - - rbt.c:2355: REQUIRE(newbits <= rbt->maxhashbits) failed, back trace

I have a full log of queries (it’s a recursive only server) and I haven’t 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’t affected.

Thanks!





Borja.
