This error occurs because MySQL has crashed or cannot start. The cause of this error is commonly not enough disk space on the disk which the MediaCP is installed on*. Another cause can be too many requests for the database causing MySQL to crash.

Steps to repair can be found in our MySQL documentation here.

*Please note that the other disks on your server may still have space, however the partition with the mediacp is full, this is what is causing the problem. If you have secondary disks with large storage we advise considering moving all mediacp media content to the secondary disk, our “Move media to another hard disk” documentation outlines the steps here,
