Hi,
Since the problem occurs sporadically it was not possible for me to debug the pipeline.
A 3rd party application places files on a file share and the receive port gets every XML by applying my custom receive pipeline. (There is no orchestration related to the implementation). Then every send port which has it’s own filtering conditions , picks up a message and posts it to a Sharepoint form library. At this time a send pipeline is also applied to the message in order to keep the initial file name of the message. (This however is not the problem, cause the problem also occurs without using the send pipeline).
If I had 2 send ports with the same filters picking a message at the same time, I think that I would always have duplicates in one or more Libraries.
I did not understand exactly what you mean by “Or, subscription is “different”, but some conditions are same”. Could you please explain?
Thanks.
