i'm using custom sink channels to encrypt (among other things) my remoting
tcp channels, but i've noticed that for every call, even though its a client
activated object, it opens a new tcp connection and leaves it open until i
run out of available sockets at around 4000 connections (8000 showing
ESTABLISHED in netstat).  The exception i'm getting is

An unhandled exception of type 'System.Net.Sockets.SocketException' occurred
in mscorlib.dll

Additional information: An operation on a socket could not be performed
because the system lacked sufficient buffer space or because a queue was
full

i'm using the Microsoft.Samples.Runtime.Remoting.Security (which i do
understand is not supported but thats not to say no one has done it) and
even its CAO demo has the same problem.  If i dont use it (just comment out
the client provider in my App.config) it works like a charm with just two
tcp connections.  Unfortunately I have no idea why its creating a new tcp
for every call rather than reusing one like the normal tcpchannel.  perhaps
something to do with the 3 way handshake it has to do?  as is probably
apparent i'm a bit over my head on this one, my understanding is fairly
limited so i'm having a heck of a time, been staring at this for about 9
hours today.

anyone know how to fix this, or even where I should be looking?
alternatively, are there any similiar libraries for
encryption/impersonation?      thanks as always.
