    Description

      I was running mariadb with galera on 3 nodes(2 nodes + 1 garb).
      One of the nodes often coredumps.
      And when the coredump happens, it calls addr2line, which takes a very long time to finish.
      While other nodes stills think it's alive and end up with huge queues of transaction.
      I tried to disable coredump so it could die completely and didn't succeed.

      Here are things I tried
      1. changing the kernel parameter kern.corecump to 0
      2. Adding core_file_size=0 to my.cnf
      3. add mysql_limits_args to /etc/rc.conf

      None of them worked.
      It always calls addr2line, which I am not sure whether it will ever finish. I always manually killed all mysql processes when this happens.

      Do I have to build mariadb with special flags to disable addr2line?
