Greeting,
Currently I am running an IIS server to serve applications , but currently I am having some trouble with the memory usage.

As you can see, Mapped File is using a lot of memory on standby, but I am not sure what application or process that causes this.
Here are some more pictures of detailed process that are currently running on my server




Do you guys have any idea what could cause this high memory usage? I really appreciate any help.
Thank you
