Well, we found that the Beta 2 patch was not stable for us and rolled back to Beta 1, I noticed the memory up to 1.3gb too last night so restarted the server.
This morning came down to a launcher.exe has crashed window and a fail to write to memory exception in the DOS box. Forgot to look at the memory useage though.
Overall Beta 1 is far more stable than the official release, the replicate time messages have disappeared. Beta 2 was a bit random, only maybe lasting an hour sometimes.
The server consists of a 12 core Xeon (dual 6 core CPUs) 1gbps (1 gig per second upload/download bandwidth) and 48 gigs of DDR3.
Oh and with the latest patch as a client it switches off my extended monitor screen
