Did you mean "2008R2SP2CU5" or "2008R2SP1CU5". Because apparently this issue was resolved in SP1CU5. Currently our server is on SP1CU9 and we are seeing user connection memory rising slowly over time. Please advice as I have been looking into this for a while and don't know what to do regarding it. Based on some of the posts I have seen some people say it was fixed after installing SP2 while some say it did not get fixed. We are currently on websense version 7.7
