Hi Ondřej, We tested the same configurations shared in the first message of this thread (having stale serve enabled) on three different BIND versions:
9.18.41 -> Crashed with assertion (within 5 minutes) 9.18.48 -> Crashed with an assertion (within 5 minutes) 9.20.22 -> Running normally with no crash so far :) for more than 24 hours Thank you.
