Hi all, I've clustered e2k installation (2 months ago) for about 1000 users. Almost everything works fine, except very high memory usage. Server has 4CPUs, 2GB RAM and after about a week without restart/move group operation I've memory usage like this: LSASS.EXE 890 MB resrcmon.exe 380 MB store.exe 970 MB I know store.exe is usually using high amount of memory and its normal, however total amount is much higher than installed RAM. How to find out what is wrong and how to fix that? Thanks for any suggestions. Chris
