SYMPTOMS

When you use a sequential convoy in Microsoft BizTalk Server 2004, you may receive a message that is similar to the following in the Health and Activity Tracking (HAT) tool for an orchestration instance:Completed with discarded messageThis issue occurs when the convoy uses a long-running transactional scope that has a time-out setting.

Additionally, you may notice that you receive fewer output and "Completed with discarded messages" messages than input messages.

CAUSE

This issue occurs when the following conditions are true:
  • A time-out exception occurs.
  • An exception handler does not handle the message.

RESOLUTION

To resolve this issue, use one of the following methods.

Method 1: Use a send port in an exception handler

To resolve this issue, use a send port in an exception handler to send the unconsumed message to another destination for processing.

Method 2: Use a WMI script

To resolve this issue, use a Windows Management Instrumentation (WMI) script to save the message to a file. Then, submit the file again for processing.

STATUS

This behavior is by design.

MORE INFORMATION

When a time-out exception occurs, BizTalk Server 2004 calls an exception handler. The exception handler should also handle the message. If the exception handler does not handle the message, the message may be lost.
