Hi,
For some reason I cannot get WEBrick to boot anymore. I installed and used Eclipse yesterday and all was working fine but today I m getting this:
$ ruby script/server
=> Booting WEBrick...
=> Rails application started on http://127.0.0.1:3000
=> Ctrl-C to shutdown server; call with --help for options

OK!
Problem Solved:
Linux solution:
In console do:
lsof|grep 3000
this will give you a line starting with:
ruby 6205 adam 4u IPv4
take the number in second position (6205 in this case) and in console do:
kill -9 6205
(note -9 is separate from the pid)
Et Voila!
Problem solved, phantom connection is destroyed.
Now, let's go back to work.

I had the same issue, and this didnt work as described (with webrick on rails 3 on a mac) - the lsof didnt return a result like shown. I used:
lsof | grep IPv4
and found a line with :
ruby 6205 myusername IPv4
which I then kill -9'ed.

If you get that error again, you can specify a different port number using "-p xxx" where xxx is the port number.

You can use an option with the lsof command to make things easier:
lsof -iTCP:3000

The solutions about work well to solve the problem.
Here's a tip to prevent it: Shut webrick down using CTRL-C instead of CTRL-Z. That was my mistake.
