How to decrease RAM usage of SQL Server 2012 without restarting Service Is there a way of decreasing RAM usage of SQL Server 2012 without restarting it?

Setting up MAX Memory usage is not an option as it's quickly building up to limit I have set and then app based on this SQL Server instance is acting up, being not responding or working very slow.

You have a performance issue that you need to investigate. Read How to analyse SQL Server performance for a starter.

Do not change random settings, like memory, in hope you fix the problem. Analyze, find the root cause and fix it.

You're probably missing an index or more.

For the record: DBCC FREESYSTEMCACHE('ALL')
