[Mongrel] Critical Issue - Site down...

I started webrick and get the same issue, I think it's a virtual  
server problem. Here is what's happening:

1) Start webrick on port 3010 in production mode (or mongrel)
2) make a request to the site
3) Production log shows a request to the front page
4) Fatal message occurs in webrick/mongrel log
5) Web browser recieves 500 Application Error response

If you refresh the page you get a proxy error response similar to  
this from apache:

Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /.

Reason: Error reading from remote server

If you refresh it again you get the normal Bad Gateway response, and  
then forever more it is that.

Here's webrick running

-bash-2.05b$ script/server -p 3010 -e production
=> Booting WEBrick...
=> Rails application started on http://0.0.0.0:3010
=> Ctrl-C to shutdown server; call with --help for options

This is the site running the Radiant CMS and it has been running  
stable for the past 6 months or so until now.
