Hi Lakshmi,

Which kogito version are you using? Are you using persistence? It would be helpful to share a test project to reproduce the issue.

Thanks,

Hi Lakshmi,

I tested your project and indeed there is an issue with multiple instances, however, this issue is already fixed and it is supposed to be in Kogito 1.15.0.Final, the next release.

There is another issue that you need to fix in the processes in the given example because it is using onEntry action in the subprocess, and currently, this is not supported in Kogito, one way to overcome this restriction is to use a Script Task before the connection with the subprocess node with the same script content present in the onEntry.

Just to add on top of Tiago's reply, you can find the current status of Kogito BPMN support in the docs: https://docs.jboss.org/kogito/release/latest/html_single/#ref-bpmn-support_kogito-developing-process-services

More precisely about this topic, in this section: https://docs.jboss.org/kogito/release/latest/html_single/#ref-bpmn-tasks_kogito-developing-process-services  

Cheers!
