Server crash during table cache eviction

    Details

    • Type: Bug
    • Status: Closed (View Workflow)
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: 10.1.5
    • Fix Version/s: 10.1.6

      None

      Description

      • we need to run out of table_open_cache to enter this code branch
      • there were ~5 active + N stale connections, though low connection number should be fine
        if they can simulate out of table cache (e.g. one connection locks/unlocks table_open_cache
        table instances, while other connections accessing other tables)
      • number of tables is not known
      • table_definition_cache may (or may not) relate to this problem
      • there should be no DDL/admin statements involved (though they're not excluded)
      • there should be no difference which DML statements are involved, so plain SELECT-s should be fine

      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 http://kb.askmonty.org/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 =
      1452041 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
