>We are having a problem with a server written in VFP running on a Win Server 2003 box with a 3.2 GHz dual core processor and 2 GB memory. The VFP server instantiates a COM server. The COM server handles communications with one or more clients or simulators across the internet. With the server running and one client connected, we run a simulator that sends a small amount of data (34 packets of about 50 bytes each every 5 seconds) across the network to the server and the server in turn sends the data out to the one connected client. For the first 3 or 4 minutes all seems fine. The CPU usage is below 1% and the memory used by the COM Server's process os about 4-5mb.

Is the COM server written in VFP or something else?

I'm also not real clear on which component is using all the memory - you main VFP server or the COM component (or both?).
