      Description

      I've set-up replication between a galera cluster connecting to one node, and each time I stop the slave the slave server crashes immediately.

      I upgraded to 22.04 and replication stopped working but the crash still occured. I reverted back to 21.10, still getting the crash but replication is still not working so trying to play with settings slave position, etc is just a pain while the server is constantly crashing on me.

      I've setup replication back in january and the problem was already there, running 10.4 I believe at the time.

      Any help would be greatly appreciated.

      This could be because you hit a bug. It is also possible that this binary
      or one of the libraries it was linked against is corrupt, improperly built,
      or misconfigured. This error can also be caused by malfunctioning hardware.

      To report this bug, see https://mariadb.com/kb/en/reporting-bugs

      We will try our best to scrape up some info that will hopefully help
      diagnose the problem, but since we have already crashed,
      something is definitely wrong and this may fail.

      max_used_connections=2
      max_threads=5002
      thread_count=1
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 11273904 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
