Quick update to say that I've seen no segmentation faults since 29 Nov on either those servers running the standard package 9.16.1-0ubuntu2.11, or running Sergio's patched 9.16.1-0ubuntu2.12~ppa1. Longest gap before that was 3 days without a segfault on any server.

The servers were upgraded over the weekend 3/4 Dec to Ubuntu kernel security update 5.4.0-135 https://launchpad.net/ubuntu/+source/linux/5.4.0-135.152

Currently I'm wondering if the trigger for the problem might be external. The servers are only accessible from the LAN, use different DNS servers (usually from an ISP) as forwarders, and the BIND querylog do not really show much of a pattern on what queries are made before the crash.

But the problem is intermittent so I will continue to monitor the situation. Has anyone else had a problem during December?
