Hi Guys

I am starting a new thread as it seems my gripe isnt to do with  
Juggernaut but with TCPSocket - which is used by Juggernaut.

Turns out that the thing that actually hangs up in Juggernaut after x  
(130/1500/16000) iterations of

(1…1000).each {|i| Juggernaut.show\_clients}

Is actually the line

res \<\< @socket.readline(CR) if response

in juggernaut.rb.

Seems @socket.readline behaves nicely when there is something to read,  
but fails miserably with a hangup when there isnt. Even a socket to my  
pop mailserver fails:

@socket = TCPSocket.new (mailserver,110)  
@socket.readline \>\> “+OK\r\n”  
@socket.readline \>\> hang

Maybe I am grasping at straws here - for a full description of my  
problem with Juggernaut on Windows see

Any ideas would be appreciated!
