Lock pages in Memory allocationg huge memory

Hi All,

One of production server Physical Memory is showing 99% . I checked in task manager SQLSERVER is using only 170 MB.

I checked remaining processes also but all are using less memory.

I checked with wintel team they are suggesting AWE is allocating huge memory.

SQL2012 Version.

SQLServer Maximum memory:16 GB

RAM:24 GB

I verified lock pages in memory , it is also using  16 GB.

Can anyone suggest to resolve this issue.
