[mapguide-users] Out of Memory error problem

[nclayton]

I'm watching my mgserver.exe in task manager, and it is currently up to
830MB+.
My OS is Windows 2003 Standard and I am using MGOS 2.0

I am hosting multiple maps. Currently there are 4 but once I get these
wrinkles ironed out there will be 20+.

Are there steps that I can perform to reduce the amount of memory being
used? Such as programatically close connections or something? Right now the
service is set to restart every 4 hours...which should remove the used
memory, but at the price of losing user sessions which is what I'm trying to
avoid.
