The parent process terminates so the subprocesses are ended. If you need anything more detailed than that to happen, then the timers will need to be handled within the child processes will need to take specific action (with their own timer nodes) -- however, you're asking me to fill in details here when you didn't provide the specific requirements. What I've provided above therefore is the simplest normal execution, where the parent process timer simply causes any/all subprocesses to halt when the timer expires.

Add a Timer node for 15 minutes in the child process, then use a gateway so either the work finishes or the timer fires. If the timer wins, terminate the child and return a timeout status to the parent.

Could you share the variables or parameters configured for the second flow? Specifically, I’d like to understand how you set up the timer, the error handling value, and the terminate node logic. This will help clarify how the sub‑process is managed when execution exceeds the defined threshold.

Shubham Aware Could you elaborate on timer-based timeout path?

Use a timer-based timeout path or, preferably, redesign the child as an asynchronous process; avoid keeping the parent waiting synchronously beyond 15 minutes.

no. the AND gateway is intentional here.

That's what the above diagram does. When the timer expires (whether or not the subprocesses are complete), the "subprocess 2" completes with a Terminate node and the parent ("Process Model 1") proceeds.

Should this be handled with an “OR” condition in the process flow?

For example, if the sub‑process runs longer than 15 minutes and gets stuck, while the first flow is still waiting to complete, how should we design the logic so that the system doesn’t remain blocked?

In the "handler" subprocess ("Model 2" in your example from what I can tell), one of the easiest ways to do this will be to use an AND gateway to create a parallel secondary flow that rests on a timeout timer, and if that timer expires prior to the two (2.1 and 2.2) subprocesses completing normally, set an error condition and terminate, in which case the parent process can observe the value of the passed-back error variable (can just be text containing your error message, etc) and take action based on that.

e.g.
