Why sql is not releasing memory?
SQL Server is indeed designed to request as much RAM as possible which will not be released unless this memory is explicitly required by the operating system.
Where can I find memory consuming queries in SQL Server?
You can monitor memory use at the database level as follows.
- Launch SQL Server Management Studio and connect to a server.
- In Object Explorer, right-click the database you want reports on.
- In the context menu select, Reports -> Standard Reports -> Memory Usage By Memory Optimized Objects.
Why is SQL Server not releasing memory after query executes?
When I run a query in SQL Server it will load in memory all the data it needs for query execution (for example, if there is a join then it would load the necessary data from those two tables) but when the query finishes executing the memory consumed by SQL Server is not released.
How to manage the memory in SQL Server?
Use the two server memory options, min server memory and max server memory, to reconfigure the amount of memory (in megabytes) managed by the SQL Server Memory Manager for an instance of SQL Server. In Object Explorer, right-click a server and select Properties.
When does SQL Server release memory to the OS?
If less memory is free, SQL Server releases memory to the OS. If more memory is free, SQL Server may allocate more memory. SQL Server adds memory only when its workload requires more memory; a server at rest does not increase the size of its virtual address space.
Can a SQL Server have too much RAM?
SQL Server is indeed designed to request as much RAM as possible which will not be released unless this memory is explicitly required by the operating system. I think the best approach is to limit the amount of RAM the server can use which will allow the OS to have a set amount of resources to use no-matter-what.
