Hello,

I have posted this question already a while ago, but at that time I was
not registered for the managed newsgroups, so I'll try it again.

In one of my Orchestrations I'm using the "Call Orchestration" shape.
It's getting called approximately 500 times a day. Unfortunately
sometimes the called Orchestration is executed twice. This is
happening once or maybe twice a day, but there are other days where it
doesn't happen at all.

In the HAT I can see that the called Orchestration was completed
successfully. No error was thrown and I can't see any other entry that
is indicating a problem.

I have put some trace points in both Orchestrations and have seen that
the message which is used as the input message is correct. In the called
Orchestration the incoming message is correct as well and therefore it
completes successfully.
But a few milliseconds later the same Orchestration with exactly the
same input message is executed again and I have no idea why this is
happening.
To me it's curios since there is no retry count which I can set for
the "Call Orchestration" shape and I don't think that it is trying to
execute again if an error occurs within the called Orchestration
(which isn't the case here, both times the called Orchestration is
doing all the work that it should do)

Has anyone noticed a similar behaviour or any idea what else I could try ?

Thanks.
Thorsten
