[Opensim-dev] Are 2000 prims, 100 simple scripts in a OpenSim region too much? How can we profile our OS installation and advise people to remove prims/scripts?

There are memory leaks in OpenSim, so restarting every so often isn't an
option. And, you are into swap a little bit there. It seems that recent mono
likes some headroom in real memory and tends to crash when the system hits
virtual memory. You might see better results with mono 2.0.1 in that
situation.
