It won't open the connection once the listen queue has filled up (if it 
did then all that would happen is the box would run out of kernel 
memory). The problem is likely that the thread which calls accept() is 
not processing the new connections as fast as they arrive. Once that 
state is achieved, the queues fill and SYNs will be dropped.
