>We have an west-wind app that is running 8 com servers on a dual processor machine. Over a few hours memory utilization starts to creep up and eventually reaches about 1/2 the available memory. Once it reaches this point, I believe the app starts to page the memory out to disk and this is terribly slow.

I doubt this is caused by Web Connection, it is used for a lot of busy web sites without memory problems. Likely there is something in your custom code that is eating memory.
