A bit more details needed:
- Does the boundary-event cancel the activity?
- Do you actually signal the receiveTask, before it goes wrong?

Yes, it does.
- Do you actually signal the receiveTask, before it goes wrong? -
Well, there is some probability a user has signalled the process instance via its frontend. But I havent found anything in my logs and could not find appropriate entries in ACT_HI_ACTINST for activities following [receiveTask] either indicating that the process instance has been continued.

What happens after the signal? Does the process ends? Are there automatic steps following?

After the receiveTask an exclusiveGateway follows as shown in the sketch.
The exGateway has 2 outgoing flows
- one which leads to more activities (but that path is not taken because of failing the given condition)
- second one leading to the process end event (no condition defined for this one)

Since the current instance is called from an outside CallActivity element we should return to the enclosing process instance finally leading to an end event.

Having had a look at my process model again I know realize that my aforementioned ex-gateway does not contain a "Default flow"-setting.
This actually used to be a problem with other exGateways of my process models. I had observed that without a "Default flow"-setting and having set a condition only on single outgoing flow only the instance mysteriously "stopped".
That could be here the case too.

I will fill in the "Default flow"-setting of the exlusive gateway and see what happens.

What do you say ?

It could be that it is indeed the case you need to use a default flow … but if it happens so rarely, it really shouldn't be the default 😉
