[OpenSER-Users] Server Crash - Sending 500

While simulating a database failure (stopping the service), I noticed that OpenSER would also crash (see log below). While I don't mind the OpenSER crash since in our configuration its highly dependent upon the database, what I would like to do is send a 5xx series message to the client so that it would be forced to look at one of our other proxies to complete its call. As the client continued to send the INVITE to the original server. How can I send a 500 Server Internal Error message back to the client in the event of a database failure?
