Hello All,

Saw something while running Exmon on our Exchange Server 1010 SP3. Please see attached. This user seems to have a lot of activity going on. Is this something that I should be concerned about?

Thanks in advance,

As far as the user that is normal.
"An Internet Information Services (IIS) worker process is a windows process (w3wp.exe) which runs Web applications, and is responsible for handling requests sent to a Web Server for a specific application pool.
It is the worker process for IIS. Each application pool creates at least one instance of w3wp.exe and that is what actually processes requests in your application."

If you have high CPU usage check this out, maybe it can help you.

Winsoup, thanks for the info. It's high memory usage that i'm concerned with. cpu usage is low.

Exchange will use as much memory as you give it. It's always trying to optimize performance so it will grab memory if there is any available to try to do that.

If you're running it on a VM you can reserve X amount of RAM for system usage. That's what I do so I don't experience issues with the system running.

I've been reading that everywhere about Exchange. I can see store.exe gobbling up RAM. Which is expected. The 7 instances of the w3wp.exe processes using memory is what prompted me to run ExMon. Thanks again for the info.
