[xmlblaster] Problem with broken XMLBlaster connections



We have a site that makes a connection to an XMLBlaster. This connection 
is regularly disconnected due to network issues. After some reconnects, 
the client successfully reconnects  but fails to get any new updates. In 
the log we see the following error:

Any idea why the client is connected but the server never sends any new 
updates? Is there anyway to force the connection close? Any thoughts? David
