  • Help on Exchange 2007 Memory Resource Problem

    Dear All,

    Our Exchange version is 2007 , previous our server only have 6GB memory include all roler and it has 200 mail box , database size about 130GB. Previous the exchange seems not stable sometime suddenly hung and I check the Windows Task Manager Performance always have only few memory free , sometime drop to 0 , we suspect the exchange is not enough the memory , so I have add 8GB monery on the server , however I have check the Windows Task Manager Performance it also only have 100mb memory free. Before the mail storage service only use about 2GB momoery , now mail storage service use more 8GB memoery , why have this Symptom occur ?How can I free more momory reserve to use
    Thanks,

    Ricky

    This is by design as far as i'm aware.

    Exchnage will grab as much RAM as possible then release it back to the OS when applications require it.

        By design Exchange will use all available memory when it can, but release it gracefully on demand, so this is normal behaviour
