PH07930: STUB CONTAINING MESSAGING LOOP CONSUMES INCREASING AMOUNTS OF MEMORY

APAR status

• Closed as program error.

Error description

• If you configure a stub event to run for long periods with
  repeated messaging actions, the stub memory footprint will
  increase over time.
  In extreme cases the stub will exit with JVM heap error
  messages.
  
  STEPS TO REPRODUCE
  
  1. Create a stub
  2. Add business logic to contain an infinite loop
  3. Inside the loop add one or more messaging actions
  4. Run the stub and trigger it.
  
  EXPECTED RESULTS:
  
  The stub runs with stable memory usage.
  
  ACTUAL RESULTS:
  
  The RunTests memory footprint increases over time and might
  crash.

  * PROBLEM DESCRIPTION:                                         *
  * Use of the TestMessageSwitchConsoleTxtVariable tag with a    *
  * never ending iterator in the activity ultimately leads to    *
  * running out of memory.                                       *
