We have a strange problem with BizTalk input queue. Our application sends
events on different times to BizTalk but occasionally BizTalk process some
of these events twice. We checked BizTalk input queue and we found some
events twice at the exactly same time in input queue. Although we are sure
that our application sent them only once for some reason BizTalk receives
them twice. We use BizTalk Server Interchange Application for doing an
asynchronous submit (we use Interchange.Submit method).
Any advice is welcomed.
