This is a generic error and can be the result of several problems listed below.
- Underperforming disk, check disk performance.
MySQL is very reliant on hard disk performance, if MySQL is running poorly it usually indicates that the hard disks are not functioning well, given that MySQL service is crashing there might be some corruption on the disk, or bad sectors. Disk performance tests can be conducted by following the steps in this link (https://www.cyberciti.biz/faq/howto-linux-unix-test-disk-performance-with-dd-command/) if the results are coming back incredibly slow it supports the suggestion of hard disk issues.
- Accessing reporting
The error occurs when there is a large number of records in the database, and it is unable to extract the records within the default timeout of 30 seconds. More information about troubleshooting this error can be found here.
