Run pidin on the same system you are running your executables.
That has to be a QNX system, right?

Thanks Maschoen.

I’ve runned the command pidin -P -l, just to see all the parent belonging child processes, and it shows me that these child processes as ZOMBIE.

Have you ever seen this? Is there some way to change this to see all the properties of the child processes, like priority, schedule?

ZOMBIE are dead child that are waiting for their parent to get their return value with wait() or waitpid(). That means the parent isn`t handling SIGCHLD.
