Hello. I am having strange error when I am creating lots of TCPSocket objects.
Here is a snippet:

require 'socket'
i = 0
while true do
socket = TCPSocket "google.com", 80
i += 1
puts i
end

On ~ 900 - 1100 iteration I get the error: getaddrinfo: Name or service not known.

Ruby 1.9.2 debian 2.6.32-5-686 #1 SMP (i686)

Sorry I coudn't find how to create this issue with the "bug" tracker.

I wanted to write TCPSocket.new of course.

I have launched the script with strace and found the problem.

socket(PF_INET, SOCK_DGRAM|SOCK_NONBLOCK, IPPROTO_IP) = -1 EMFILE (Too many open files)

As strace showed, you opened too many files (sockets).
You must close sockets before open new one.
This is Linux's limitation.
