      Description

      Hello, my name is Cassil.
      I am a new employee engineer.
      I don't know if it's okay for me to write here.
      I'm not good at English. Please excuse me.

      Our company uses mariadb.
      MariaDB is being used as a POD of k8s. Maria DB POD continues to be restarted with Error and CrashLoopBack occurring in our products.

      I don't know what the cause is. Could you please check the 'LOG' for what error this is?

      220228  7:23:02 [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 helpdiagnose the problem, but since we have already crashed,something is definitely wrong and this may fail.

      The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains 
      information that should help you find out what is causing the crash.  Fatal signal 11 while backtracing  
      
      

      To solve this error, what should I look at first?
      ..Do you have any idea?

      thank you
