Sometime last week a super user was monitoring the Task Manager Processes to find out why his appliction was running so slowly and started running on disk. He told me that the SQL Service went down to 400m for the entire SQL Server instance. This morning I am looking at the Processes and show that the SQL Service is at 104,556K.
What would have caused that to happen?

Thanks

A sudden drop in memory usage is typically due to the cache being flushed. Check for what SQL jobs run at that time or if anyone ran DBCC commands around that time.
