Hi,
week ago our production database cluster (1 master, 4 replicas, maxscale as proxy) started to deadlock master approx. every 12 hours. We are still looking for trigger but without any success. No obvious problematic query in PROCESSLIST, nothing 
Finally today we were able to get decent coredump, using quay.io/mariadb-foundation/mariadb-debug:10.6 image. Exact version is 10.6.16-MariaDB-1:10.6.16+maria~ubu2004-log source revision: 07494006dd0887ebfb31564a8fd4c59cf1b299e9, exact image version docker.io/library/mariadb@sha256:fcbe381e5fef20c7a2932b52a070f58987b770c651aedf705332e54d1dfd465f
SELECTs seems to be running OK, DML queries are blocked. Some in "opening table" some in "sending data".
I'm attaching both server log, full backtrace and I also have coredump, but it is 700MB bzipped so not attaching but is available.
