      Description

      galera.galera_bf_lock_wait failed on 10.3 ES|]: "sync0policy.ic:64: void MutexDebug<Mutex>::enter(const Mutex*, const char*, unsigned int) [with Mutex = TTASEventMutex<GenericPolicy>]: Assertion `!is_owned()' failed".
      It seems to be a sporadic issue and it does not fail on BB.

      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.

      thread_count=11
      It is possible that mysqld could use up to 
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 63311 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
