You can find the clue on your own by carefull reading of the provided error message:
"No managed connection available within configured blocking timeout" This simply means that your connection pool for your mySQL DB ran out of connections. You can monitor the connection pool state (e.g. number of available connections) with the jmx-console. For a determination of the underlying problem cause you have to provide more detailed information. Which JBoss version ? How many concurrent clients and things like that.
