    Description

      Notes:

      1. This is a random kernel panic
      2. It can happen hours after reboot or days or even weeks
      3. The last time it happened was a month ago.
      4. We didn't realize a month ago that this was related to a zabbix process
      5. We understand that a zabbix process should not be able to cause a kernel panic, but we are just opening the ticket in case it's helpful

      Result:
      See screenshot of kernel panic

       

      Now that we have a clue that it was due to the odbc poller #1 process, we have disabled it in /etc/zabbix/zabbix_server.conf 
      StartODBCPollers=0
