Hey there! That seems like a normal email notification to me. You'll want to check the MySQL error log to see if that provides more details about the cause of the crash. Typically the error log is located at /var/log/mysqld.log unless the server's configuration has been customized.

In the log I found this... and it always happens at the same time

Thanks for posting that - most of that looks like a normal restart except for the "access denied" section at the very end. However, although those look concerning, they can be ignored:

Could you submit a ticket to our team so we can check the MySQL issue on the server directly?
