There are several things it could be. You could be running out of
connections or you could be closing a connection and then trying to access
it. Not sure its entirely struts related..

Down in there you have a "java.net.SocketException: Connection reset"
...and repeated "The connection attempt failed." log messages right at the
top there. Something's going on between you and your database server;
looks like a network problem, or maybe somehow something monkeying with
your database's ability to accept connections.
