General :: Phone Reboots After Script Execution (root)

i was developing a tasker and to kill the apps i was using this script

Code:
String command = "pidof -s " + intent.getComponent().getClassName() + " | kill -9 .";
Process su = Runtime.getRuntime().exec("su");
DataOutputStream os = new DataOutputStream(su.getOutputStream());
os.writeBytes(command + "
");
os.flush();

I tested doing that in the terminal and works fine, but in my tasker, when this command executes the phone reboot...
