I've fixed the problem with not finding the variable in called activity. I'd hadn't mapped the elementVariable in the input parameters.

It's still strange that the service to create the collection seems to run multiple times.

The running multiple times may be transaction roll back and retries. I've just been working on a similar problem where I haven't set process variables correctly. I just see my service task run and fail 3 times 10 seconds apart. I assume a rollback is occurring then the transaction is retried. No error is shown presumably as the exception isn't caught.

In your case you have 2 sub processes, so it could be the same behaviour, if each fails and retries 3 times that gives 6.
