In one of my servers the sql server is utilizing the ram memory for about 22GB out of 30GB. And the allocated memory for the sql server is 20GB, Please let me know how to find that which is using this memory and how to rectify this problem. My Sql server 2008 with SP1 64bit is on windows 2008R2 64bit. I have checked in the task manager in that i can see SQLServr.exe is utilizing 17GB.I monitored in Activity monitor to find the blocking or locks but i couldnt find one. There are no slow running queries.
