Openfire service shutsdown by itself

Hi,

I am having an issue where at roughly the same time everyday the openfire service shuts itself down. Looking at the log it seems to be a problem connecting to the database but i’m not sure why.

The error log can be found below (sorry I don’t know how to add it as a spoiler).

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

java.sql.SQLException: ConnectionManager.getConnection() failed to obtain a connection after 11 retries. The exception from the last attempt is as follows: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
