Your shared host will likely have to kill the jobs/connections or restart the mysql daemon. Next, you will need to figure out why your connections are hanging and update your code to resolve the issue.
If you are not certain where to start you could monitor the connection script by logging any errors with a full trace and dumping it to a log. (Throw a new exception error within a try/catch block).
