PI72860: APPLICATION PROCESS EXECUTION CANCEL BUTTON DOES NOT CANCEL IN SOME CASES

APAR status

• Closed as program error.

Error description

• In some cases, application processes are not completely canceled
  when a "Cancel" action is taken.  Instead, running steps cancel,
  and steps following steps continue as if the canceled steps
  succeeded.
  
  To reproduce:
  1. Create a component operational process (no version needed)
  with a simple shell step that sleeps for 10 seconds. (So that
  the component process takes more than a few seconds to run)
  2. Create an application process calling that component
  operational process 3 times in a row.
  3. In the application process, mark the edges between the
  operational processes as "Grey", or "Always".
  4. Run the application process.
  5. Immediately cancel the application process.
  6. Note that while the first instance of the component process
  canceled correctly, the second instance of the component process
  may start running anyway.
  

Local fix

• If it doesn't cancel the first time, canceling the application
  process via the CLI multiple times will eventually result in the
  application process cancelling.
