ZeroMQ C# Port Opening

[FEDESPAGNOLO]

Hi all,

I'm just developing a C# client application that requests some data to some
servers.
I'm using ZeroMQ Client/Server pattern to perform this solution.

The servers are linked by wireless connection, so the connections are not
always guaranteed.
I noticed some problem using ZeroMQ when some communications expired with
the timeout.

In order to debug this problem, I created a simple project that call a
no-connected server.

Using a port sniffer, I noticed that a huge quantity of ports are opened
and not closed, as you can see by the attached file (shooted after
few requests).

My software scenario is:

• Windows 7 Home Edition 64 bit
  • Microsoft C# Express 2012
• clrzmq version 3.0 downloaded by NuGet.
• libzmq.dll compiled in C++ on my machine.

Using google is not simple to find some C# ZeroMQ support so I hope your
experience could help me.
Thanks in advance.
