The fix worked properly. Thanks for the help!

Thanks for the quick replies and the suggestions. I will modify the process model and will update this thread once the process executes successfully.

Just to cut to the chase, I would replace your complex gateway with a combination of an AND and 2 XOR nodes. See nodes in red below.

Here you go. Please note that the process is currently halted on the last script task which I highlighted earlier.

Yes, exactly.

A screenshot of an already-run instance but without having manually started the nodes.

Yes, per what Carlos was hinting at, if the bottom flow reaches the Terminate node before the top flow does, then everything in that process instance will be instantly halted even if it's in-progress. That is the designed behavior of Terminate nodes.

If you can provide a screenshot of an already-run instance of just the top model, we can visually confirm this.

Yes, as per the implementation, both the outgoing flows are being used, and yes, the "down" flow ends before the "right" flow. Is this something creating trouble here?

You have a complex gateway in the first screenshot. Both outgoing flows end in terminate nodes. Any chance that: 1) both flows are getting used, and 2) the "down" flow ends the process instance before the "right" flow reaches its end node?

I am attaching the screenshots of the process models. The nodes marked with red are the ones with issues

None of the PV is checked as required in any of the sub-processes. Yes, the PV in the sub-process which is mapped with the PV passed from the parent process model is marked with Parameter.

Hi Abhisek Bera

Just to understand more, what is the chaining size of the pm's including these nodes? Are the nodes breaking or just hang? Are there any pv's inside sub process models which have thier "required" checked? Is it possible for you to attach a screenshot for any of these nodes to better understand the situation.
