Strange WEBrick Error

I was messing around with ruby on my Windows box and for some reason WEBrick kept crashing on me with the following output:

ruby script/server
=> Booting WEBrick…

A quick google indicates that I’m not the only one having this issue but it does seem very rare. Curiously enough the solution turned out to be using a different port for the server. For example I did:

ruby script/server -p8080

That seemed to work just fine. Strange… I’m wondering if this might have something to do with my AV or Firewall blocking connections on port 3000 for some reason…
