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.
