Sometimes MySQL server crashes, it shows up on the site as an error, which says, they say, it does not find mysqld.sock, it is not created on the server itself either. The error message "InnoDB: Unable to lock ./ibdata1, error: 11" is displayed in the logs, it is treated by restarting MySQL, or by killing the process and launching it. Tell me what can lead to this error, and how to deal with it, it happens in a chaotic manner, thank you.
