Sounds like you need to decrease the amount of time that idle connections stay around in the server before they are disconnected. > Is there any way to kill all of the hanging processes?

That means there will be more open connections to the database server. If you have a sufficient number of Apache (or whatever) children, you can easily over-run MySQL. Jeremy -- Jeremy D.
