FMS web publishing "freaks out" when pages have error

While developing a new CWP solution, some of my pages have errors, like incorrect URLs. Whenever I call a page with an error, FM Web Publishing "freaks out" on my test machine running OSX Snow Leopard Server. Activity Monitor shows CPU activity in the 60-90% range. During this period, the web server serves pages very slowly, if at all. The database server shows high activity, too.

FM Web Publishing eventually settles down to 0.1%, but it takes several minutes or more. Using the FMS Console to stop Web Publishing does not stop the activity. I have to also quite the database server to get it to stop.

It's not infinite loops causing this. A simple incorrect URL will cause the problem (as well as other mistakes).

Running FMS 11.04.404. Snow Leopard Server updated to newest.

I don't recall ever seeing this problem before with FMS. It seems like FM Web Publishing should handle such errors much better.

What to do? Must I reinstall FMS?
