This was replicable in the following scenarios:

  1. Starting the processes while pmond was active
  2. restarting pmond (pmon2.service) after

killing the processed while pmond is running respawns the process with the appropriate ppid. further testing also reveals that pmond restarts do respawn the process with the correct ppid. This is most likely related to using the sudo command. however forking a process as non root user is currently not possible.

[terraform@puppet pmon2]$ pmon2 run bin/test_server --args "-h 10.132.204.203 -p 5555 -r 5000"
