script/server hangs webrick and mongrel

When I script/server, both webrick and mongrel hang until I ctrl-c.
If I'm using webrick, it will start normally, but if I'm using mongrel
it will appear to start and then hang again. Any idea why this

Have you taken a look at your development.log file right after the
hanging begins? If there's something you can't make sense of in there,
post it here.
