You cannot resume messages from BizTalk Server 2004 Health and Activity Tracking after Internet Information Services is stopped and then is restarted

View products that this article applies to.

Symptoms

You use dynamic ports to send messages through the HTTP transport by using multiple instances of the same orchestrations. During the execution of the Business Process Execution Language for Web Services (BPEL4WS), Microsoft Internet Information Services (IIS) is restarted and some of these messages are sent to the suspended queue. Events that are similar to the following are generated: 

Uncaught exception terminated service 
HTTPMultiIn.Service1(2eb5be0d-6a94-374a-ba72-21fb7336bca6), instance 
905dc7e4-b8c6-4b01-be28-9e595b476198

Exception from HRESULT: 0xC0C01B13.

Additional error information:

The BizTalk HTTP receive location "/WSOPortTest01/BTSHTTPReceive.dll" could not 
send the HTTP headers to the client.

The BizTalk HTTP receive location "/WSOPortTest01/BTSHTTPReceive.dll" could not 
send the BizTalk correlation token to the client.

The "HTTP" adapter is suspending a outbound message going to destination 
URL:"HTTP://localhost/WSOPortTest01/BTSHTTPReceive.dll". Details:"The underlying 
connection was closed: An unexpected error occurred on a receive.".

The "HTTP" adapter is suspending a outbound message going to destination 
URL:"HTTP://localhost/WSOPortTest01/BTSHTTPReceive.dll". Details:"The remote 
server returned an error: (503) Server Unavailable.".

The Messaging Engine has suspended "4" message(s) from adapter "HTTP" due to 
failures in message processing. Please refer to Health and Activity Tracking tool 
for more detailed information on this failure.
Even though IIS is running again, the messages cannot be resumed by using Microsoft BizTalk Server 2004 Health and Activity Tracking (HAT).

Cause

This behavior occurs because you cannot resume response messages when they are suspended. The response is delivered to an adapter on a callback interface. When the adapter terminates for any reason, you lose that callback interface because the interface resided in memory. Additionally, you cannot pass that response back to IIS because the IIS extension control block that holds a reference to the connection will have terminated. Additionally, you cannot resume all messages that are suspended on the receive side.

Status

This behavior is by design.
