Hi,

I have an issue which needs to be resolved.

I have a msgflow, in which it has a Compute node which has a while loop.
The 2nd last line of the loop is to porpogate a HTTP request, which is part of a separate flow within the same msgflow but reachable via a Label node, as below:

PROPAGATE TO LABEL 'LABEL_NAME' FINALIZE DEFAULT;

After this the while loop just increments the counter on which it is looping and then start the while loop again.
SET COUNT = COUNT + 1;

The incoming msg (which is an XML) has multiple values for which an HTTP request has to be sent for each of the values.
To do this we have implemented the above while loop, which gets the total count of the value and then loops for each value to send the HTTP request.

Now the issue is, that we succesfully send the HTTP request for the first value.
However, the control does not come back to the while loop once the request is sent.
We have done user tracing on this as well, but we do not see any error.
It just abruptly stops.
The response from the Web Service is also succesfull.

Now the catch is, the same msgflow when deployed in another environment work perfectly fine.
Also to make a note, the web service in both the environments are implemented a bit differently.

But the catch is I am not able to understand:
1. The Web Service is not returning any error.
2. The user trace for the msgflow is not tracing any error.

Please let me know what I can do to at least understand to get hold of the error.

Env:
AIX
WMBv6.0
MQv6.0.2

Thanks.
