Well not so much a leak but since upgrading to Snow Leopard I've noticed that over time, a big chunk of my RAM is being siphoned off into a process called OSMServer. Does anyone know what it does and why? And more importantly how to stop it doing it? It's currently using over 1GB of my 4GB RAM and making the machine run like treacle. The only way to clear it seems to be a full shut down and restart. Which is fine for a while until it fires back up and starts gobbling RAM again.
