    Details

      Description

      We have a slave server.
      I have seen the following message in the mariadb error log.

      170604 16:40:01 [ERROR] mysqld got signal 11 ;
      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.

      Server version: 10.2.6-MariaDB-log
      key_buffer_size=48318382080
      read_buffer_size=1048576
      max_used_connections=2172
      max_threads=65537
      thread_count=641
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 181468904 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
