Because I don’t know what code you are using, I don’t know what you are doing wrong.  However, because our existing “LIVE555 Proxy Server” code (in “live555ProxyServer.cpp”) is working OK for you, you should use this code as a model for your own application.

Your problem appears to be that you are deleting LIVE555 objects in the wrong order.  In general, it is usually much simpler to exit your application by calling “exit()”, rather than by trying to delete LIVE555 objects and keeping the process alive.
