SQL Server uses a lot of memory
Here's a little work around for SQL server which uses a lot more memory than it should. Naturally, you can set this through the properties of the instance it self. however, since this is a bug in microsoft sql server 2008 (r2?), this script is a workaround.
EXEC sys.sp_configure N'show advanced options', N'1' RECONFIGURE WITH OVERRIDE GO EXEC sys.sp_configure N'max server memory (MB)', N'{low water mark}' GO RECONFIGURE WITH OVERRIDE GO EXEC sys.sp_configure N'max server memory (MB)', N'{High water mark}' GO RECONFIGURE WITH OVERRIDE GO EXEC sys.sp_configure N'show advanced options', N'0' RECONFIGURE WITH OVERRIDE GO
Low water mark : Minimum usage
High water mark : High usage max.
