Real Server\Producer Problems

I’ve been running Real Server 8.5 Basic and Real Producer for live web Broadcasting. It seems to run fine for about 30 minutes to an hour and then the server Crashes. It usually gives a Buffer error and or a General Error, frezzes and then re-boots.The O/S is Windows 2000 Server and I’ve loaded every service pack I can find. RealNetworks is no help and I’m not too sure what else to do! There computer is more then capable to handle it, but I can’t seem to find what’s wrong 🙁
