      Description

      See below error dump & attached core dump, happens sporadically resulting in dropping of all connections and evacuation of cache taking around 20 seconds to recover. In each case it is a random simple select that causes the issue. All tables are innodb and have been mysqlcheck'd with no issue found. Issue did not occur under 10.4 but coincided with move to 10.5. System is not under excessive load at the time the problems manifests. Problem also was manifest in 10.5.5

      InnoDB: Submit a detailed bug report to https://jira.mariadb.org/
      InnoDB: If you get repeated assertion failures or crashes, even
      InnoDB: immediately after the mysqld startup, there may be
      InnoDB: corruption in the InnoDB tablespace. Please refer to

      201201 11:11:36 [ERROR] mysqld got signal 6 ;
      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 = 2660907 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
