      Description

      Our database sometimes crashes after midnight. We can't figure out why

      • The CPU load / memory usage seems minimal
      • Happened on the 6th and the 8th of this month, not since

      This is a trace from the 6th of January

      2018-01-06 0:16:00 140365306332928 [Note] Event Scheduler: [root@%].[obfuscated.sphinx_indexujProdukty] event execution failed.

      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.

      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 347227 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

      Query: INSERT INTO produkt__hodnota_atributu
      SET
      id_produkt = '8883',
      id_atribut = '3',
      id_vazba_atributu_na_skupinu = (SELECT id FROM produkt_atribut_vazba_na_skupiny WHERE id_atribut = '3' AND id_skupina_atributu = 1),
      typ_hodnoty = 'varchar',
      hodnota_varchar = '188.000000',
      datum_vlozeni = NOW()

      This is causing us some unfortunate issues. I wonder if modifing the "optimizer switches" couldn't help us - at lease temporarily....
