Hi!!

I have a very strange problem.

I have a pair of client and server. Server exposes just one object (Server
activated object) and for the problem I have it does not matter whether it
is a SingleCall  or Singleton.

I use standard TCP channel with binary formatters. On the server side I
register the channel with
RemotingConfiguration.RegisterWellKnownServiceType.
On the client side I use Activator.GetObject to obtain the remote object
reference.

After that I use and endless loop to call the server object.
It does not matter whether client and server are on the same machine or not.
It also does not matter if the server activation type is SingelCall or
Singleton. Every now and then (usually after 3 or 4 thousand calls) I get an
exception on the client side :

System.Net.Sockets.SocketException: Only one usage of each socket address
(protocol/network address/port) is normally permitted.

Server stack trace:
  at System.Net.Sockets.Socket.Connect(EndPoint remoteEP)
  at System.Runtime.Remoting.Channels.RemoteConnection.CreateNewSocket()
  at System.Runtime.Remoting.Channels.SocketCache.GetSocket(String
machineAndPort)

That is strange because I am not trying to start a second copy of the server
or anything like that. The exception is always on the client side.

Why is this happening?

Please let me know if there is some explanation for this.

Thanks a lot.
