      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: 10.1.23-MariaDB
      key_buffer_size=134217728
      read_buffer_size=131072
      max_used_connections=5
      max_threads=1502
      thread_count=2
      It is possible that mysqld could use up to 
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 3430253 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

      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: 10.1.23-MariaDB
      key_buffer_size=134217728
      read_buffer_size=131072
      max_used_connections=5
      max_threads=1502
      thread_count=2
      It is possible that mysqld could use up to 
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 3430253 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

      As you can see, we got the buffer overflow 2 times in a row. Currently the server managed to start and it's replicating.
