Ruby Sockets Vulnerable?

[unni.tallman]

I have a TCPServer listening on a port. I forked a 500 odd TCP Clients
and tried to connect to this TCPServer. Around 300 clients got
connected, others gave the error :

Connection timed out - connect(2) (Errno::ETIMEDOUT)

I wasn't able to connect anymore clients to that server. Does this mean
that ruby TCPServer can serve only a limited number of clients?

It is a limitation of the underlying network functionality not of Ruby.
If you are on Windows non server version a very strict limitation is
actually built into the OS.

Note that it is generally not a good idea to allow arbitrary numbers of
clients to be served.
