	I'd think that the pgrep is matching both the processes you want
	to kill _and_ the init.d script itself.  Try "pgrep -x" which
	will exactly match the specified command.

	Even better, use "pkill -x -9 my_app" which will combine the
	grep and kill tasks in a single command; the -9 specifies the
	signal to send to the matches processes.

	"man pgrep" for more information on both commands.
