SQL Server ate a lot of memory
Posted on 2009-05-07
I have a SQL server with 3 instances inside . SQL2005Std,SQL2008 and SQL 2005 Dev Ed. The physical server which holds the instances is 12GB RAM. At all time , the task manager shows that the memory is heavily utilized as follows:-
Physical Memory (K)
System Cache 498440
And the PF Usage shows 12.1GB is being used.
When I check , it shows SQL services is using most of it . And I do get an alert " Windows is low on virtual memory " frequently.
I did get to know about this script :-
EXEC sys.sp_configure N'max server memory (MB)', N'1024'
RECONFIGURE WITH OVERRIDE
but I'm worried if it will impact the performance of the SQL itself as it cannot get as much as and when needed.Because the script tend to limit the RAM used by SQl. Please advise on how to overcome this problem.
