When disconnecting from WebSphere MQ with C # client connections, the client is still in CLOSE_WAIT state

Question

I am disconnecting from MQQueue and MQQueueManager with the following code:

Queue.Close ();
log.Info ("Queue IsOpen:" + Queue.IsOpen.ToString ());
Queue = null;

QueueManager.Disconnect ();
QueueManager.Close ();
log.Info ("QM IsOpen:" + QueueManager.IsOpen.ToString ());
log.Info ("QM IsConnected:" + QueueManager.IsConnected.ToString ());
QueueManager = null;

And I get the following log entries for this:

Queue IsOpen: false
QM IsOpen: false
QM IsConnected: false

But a few hours after running the netstat -n command from the command line, I get a long list of connections to the MQ server, and the status in these connections is CLOSE_WAIT .
