Openfire / MySQL connection resets every few minutes

I am an old hand at most Linux tasks, but openfires JAVA based error messages have me quite stumped.

I have installed openfire 3.4 via the tar file, and the deb file, and both exhibit the same problems.

Openfire, looses its connection to the mysql database every few minutes, and it fouls things up. The database is on the same server as openfire (connecting via localhost), and I am not sure where to start trouble shooting - because the openfire error message is like Hebrew to me.

Can any of you experts shed some light on this? The connection fixes itself after a few seconds (20-30) and then you can log in etc as needed. It will break again in 3-5 minutes.

Here is what my connection page looks like normally:
