Sucks the memory!

Jun 27, 2013 at 9:20 AM
On windows server 2008 R2/x64 after connecting to a local site , it starts to processing but after about 10 minutes the OS started to hang! I checked the cpu/memory usage for each process and see it takes 3.8 out of 4.0 GB memory!!!

P.S. I installed the X64 Version
