sqlsrvr.exe is not using all memory I have no clue what to set up more.
I tried a lot. 

My Problem is that on my test Server everything is runing perfectly see 


but on my production Server its not! see 


I found this on my Production Server:
"Using locked pages for buffer pool"

This is shown in the error log of the SQL Server.
This line only Shows up in the production System.

Both Systems are SQL 2008 R2 Enterprise with WIN2K8 R2 both in 64 bit.

Locked Pages in Memory is not enabled in GPEDIT.MSC

Can someone explain that to me?
AWE allocated pages are not reported by Task Manager. The "Using locked pages for buffer pool" message means the production server is using AWE. Do not trust Task Manager. Use SQL Server own counters: SQL Server, Memory Manager Object, SQL Server, Buffer Manager Object.
