      Description

      we recently upgraded a host from 5.5.50 to 10.1.24; and now get the following error when a certain stored procedure is executed. It does not happen every time and immediately after restart - the stored procedure call finishes without issue. I dropped and recreated all the stored procedures on the host in case it was some sort of corruption, but after a couple days - the server crashed again reporting the following in the error log:

      180628  7:01:35 [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: 10.1.24-MariaDB
      key_buffer_size=5368709120
      read_buffer_size=270336
      max_used_connections=251
      max_threads=1252
      thread_count=236
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 8163227 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
