[zeromq-dev] zero MQ 2.0 app remote shutdown when probing port with nmap.

[Skrzyniarz Alexandre]

Hello.

Probing a port used by a zmq application causes application shutdown:

./local_lat lo:5555 1 1
nmap -p 5555 -P0 localhost
--->
Assertion failed: false (zmq_listener_init.cpp:95)
Aborted

(it's in the detach funtion).

nmap opens a tcp connection, then sends a RST,ACK packet that triggers 
shutdown.
