  • Is it a problem that SQL-Server is using a lot of memory? Commented Jun 6, 2012 at 8:28

SQL Server is supposed to use all the memory. If you want to reserve memory for other things set the max server memory setting in SQL Server so that it'll stop eating up all the memory.

  • I would always suggest to set a max memory, otherwise you can run in memory problems even on dedicated machines.

SQL Server will always use as much as memory as he can gets. Even on a server which is designed just for SQL Server, you should define a max memory usage on the instance. Otherwise your windows can run in a memory pressure if you try to connect to the machine as admin.
