The RAM bloat stinks of "infinite loop" to me.

I don't know ASP or CF well, but PHP has a "max memory" option. Do
they have similar things?

That is a HUGE amount of RAM to be using, given that we're talking of
only 20-40 concurrent clients.

I think you need to get your programmers to have a serious look at
their scripts........ :)

Flawed scripts: could be, but, at least with ColdFusion, I'd expect
the task manager to list the CPU cycles under CF's process, rather
than Apache's. We're trying to figure out how to eliminate the
ChiliSoft ASP engine as the culprit.

Database access: the ASP pages only access local Access files. 

The box is a Compaq Proliant DL380 (1.26 GHz processor, with 512K
cache, and 312 mb Compaq ram) 

The site is for a medical society; you can see it at www.ascp.org.
The ASP pages don't do anything fancy. We do have an e-commerce site,
but that's all handled by ColdFusion.

I don't know if it's relevant, but occasionally the amount of ram
Apache uses bloats from 19mb to 300-600mb, though this doesn't seem
related to the CPU usage and performance problem.
