According to upstream this is harmless and it has been mentioned as such in the release notes of 9.16.11 --- The report of intermittent BIND assertion failures triggered in lib/dns/resolver.c:dns_name_issubdomain() has now been closed without further action. Our initial response to this was to add diagnostic logging instead of terminating named, anticipating that we would receive further useful troubleshooting input. This workaround first appeared in BIND releases 9.17.5 and 9.16.7. However, since those releases were published, there have been no new reports of assertion failures matching this issue, but also no further diagnostic input, so we have closed the issue. [GL #2091] --- Please check whether you still see this in 9.16.11 (just uploaded). Bernhard
