I think we've seen that in both Apache and the OpenMarket WebServer.
Our solution: abort the server and restart it.

It *might* be associated with a bug I've seen in handling non-byte-stream files
by the byte-stream emulator (maybe), and then again it might not be :)

Have you noticed free disk space disappearing during this time, and heavy
disk activity?  If so, then it might be related.

I haven't had the opportunity/time/inclination to try to track it down
further...but the next time it happens, I'll look more closely.

You might try getting a Debug/iX snapshot of the CPU-eater...

assume it's pin 123 (:showproc job=#j999 will show you the pins)

   logon as manager.sys

   :run httpd.pub.apache; debug
        (or whatever the Apache httpd program name is called on your machine)

When you get the Debug prompt, enter:

   pin #123; tr, i, d

If the stack trace is only one or two lines long, redo the pin/tr command.

Then:

   abort

(this abort the local run of httpd ... not the CPU-eating process)
