title: NService bus message delay problem
body: <p>Yesterday I did a production simulation. The results where not good. The connection between the two servers is OK. From time to time there is huge delay, about 5-10 minutes. I send a message, two, three.. twenty and the other side do not receives them. And then boom, all messages are there and the reply is send to the sender. The other situation is when I send 10 messages, the other side receives them momentarily and replies. But the replies are not received by the sender. After 5-10 minutes BOOM, the replies are here.</p>
  
  <p>What is goin on. please help me.</p>
  
  <p>====================<br>
  EDIT:
  Both servers are windows XP sp3. Both computers are connected with openVPN.
  NSB is the latest version.</p>
  
  <p><strong>UI</strong> &lt;= <em>duplex</em> => <strong>applicaiton server</strong> &lt;= <em>publish/subscribe</em> => <strong>Denormalizer(readonly database)</strong></p>
  
  <p>Yesterday I tested only the duplex. In a 1PC environment everything goes smoothly. When the duplex is ready I will test the 3rd part.</p>
