Author Strange behaviour after correlation

Hi,

I have noticed a strange behaviour in our orchestration after a message is
received from a third-party. The message is correlated properly with the
orchestration instance (due to the fact that the third party receives a
success response from the Biztalk HTTP adapter).

However, after this the next steps in the orchestration are not executed at
all. When I open the HAT, I see that the status of the orchestration instance
has changed from "Dehydrated" to "Active", but nothing happens. Also, when I
choose "Service Details" for this orchestration instance, I get a list of
messages - one of them is of type
"Microsoft.BizTalk.XLANGs.BTXEngine.BTXTimerMessage" with status "Delivered,
not consumed".

Can someone please explain how to handle this behaviour. This is happening
randomly for some instances of the same orchestration, but the rest work fine.

Thanks

I've run into a similar issue... do you use any scopes in your orchestration?
if yes, are they transactional? If you suspend the orchestration, and then
resume it, does the orchestration continue normally?
