I keep getting Internal Server Errors when running my website from within NetBeans 7. Below is an example of the output I get.

Once the error occurs I get Internal Server Error every time I try to load a page, until I restart the server.

The error does not appear to be specific to a particular page, or process. In the example below, it appears to have occurred while getting data from the database. It can as easily happen during rendering. The consistent aspect is the failure at log_tailer.rb:25:in `write'.

I don't get any problems running the site from Netbeans 6.9.1. The site is also working fine on an internal test server (Rail production environment), and when running webrick from shell on both Windows 7 and Ubuntu.

I'm running NetBeans 7.0 (Build 201104080000) and added the Ruby plugin (1302981014_nbruby041611). I'm running Windows 7 32 bit. My project is using Ruby 1.8.7-p302, with WEBrick as it's server. Rails is version 3.0.6.
