I'm using Domino 6.5 on a Windows 2003 Server platform. The Domino server uses more and more memory until the server crashes. When I look in the Task Manager, nearly each Domino task uses more than 1 GB of RAM. IBM created a fix pack, but only the time to shut down the Domino server was reduced and not the main problem.
I'm not sure what the specific memory leak issues are with Domino, but until a comprehensive fix is available you may want to try loading a Memory Recovery Tool such as MemTurbo. This tool monitors memory usage and will automatically try to recover unused RAM when critical levels are reached. I've used it in a similar situation when a SQL database application was using all of a server's memory until it crashed as well.
