    Dear All,

    We have sql server 2008 with two node cluster.

    during operation memory is reaching up to 90% but its not releasing after decreasing the load.

    Memory is freezing at one limit.After restarting its coming down but automatically its not coming down.

    Pls suggest how to rectifiy this

    Normal, expected, documented behaviour.

    SQL uses a lot of memory. It won't give it back to the OS unless the OS come under memory pressure as it's inefficient to be constantly allocating and deallocating memory.
