InnoDB Troubleshooting Overview
Contents
As with most errors, first take a look at the contents of the MariaDB error log. If dealing with a deadlock, setting the innodb_print_all_deadlocks option (off by default) will output details of all deadlocks to the error log.
It can also help to enable the various InnoDB Monitors relating to the problem you are experiencing. There are four types: the standard InnoDB monitor, the InnoDB Lock Monitor, InnoDB Tablespace Monitor and the InnoDB Table Monitor.
Running CHECK TABLE will help determine whether there are errors in the table.
