Hello

We have a main process which contains the sub-process configured as Asynchronously. This main process runs on MNI.
In case of the 2 instances of main processes which subsequently created 2 instances of this a-sync sub-process. if any of the sub-process gets terminated then one instance of main process is completed , but the other one gets aborted and do not generate any alert as well.
Note- In sub-process termination process is configured on End event

Can anyone help me to resolve this problem?
