Situation:
Subflow with AggregateControl node that fans out to 6 targets. The AggregateReply node in the same subflow receives the 6 responses and collects them.

The AggregateReply node is connected with a ESQL compute node which creates an xml message in the XMLNSC domain. The next step is a SOAP Envelope node which add a SOAP envelope arround the xml message. The last step is a simple Output node to exist the subflow.

Problem:
Sometimes the message gets stuck in the SOAP Envelope node (before the output). Both the out and failure terminal of the SOAP Envelope node are connected, but no action is seen.

Sometimes the message passes without a problem, sometimes is doesn't. However the message is always the same.

In the user trace I see that the SOAP Envelope is the last step and then the thread terminates:

Code:
2009-05-11 11:50:03.190100     2380   UserTrace   BIP2537I: Node 'subflow.A793_CWW_GetDetailWagonCycle.ComposeReply': Executing statement   ''RETURN TRUE;'' at ('subflow.A793_CWW_GetDetailWagonCycle_ComposeReply.Main', '77.3').
2009-05-11 11:50:03.190212     2380   UserTrace   BIP4007I: Message propagated to 'out' terminal of node 'subflow.A793_CWW_GetDetailWagonCycle.ComposeReply'.
2009-05-11 11:50:04.937507     2380   UserTrace   BIP3904I: Invoking the evaluate() method of node (class='ComIbmSOAPEnvelopeNode', name='subflow/A793_CWW_GetDetailWagonCycle#FCMComposite_1_21').
                                       About to pass a message to the evaluate() method of  the specified node.

Threads encountered in this trace:
  1248  1336  2380  2392  3868  3916  4172  5104  5232  5504  6132


Solutions I've already tried:
- Create the SOAP Envelope with a simple compute node. Now the problem occurs in the compute node. So the problem occurs only in the last node before the output node ...
- Set the ExpirationTime to -1, maybe the message expires in the last node ... Nothing changed.

I hope someone here can help me!
