Thanks Perderabo for noting my nonsense, I was disturbed friday by phonecalls and people in my office when trying to post and got mixed up...the exec I was thinking about was on calling script 3, not inside...(silly because in present case there is no mention of exits...)
Anyway you are right here it looks more the script found its parent and explicitly killed it like a bugged ps -ef to get all process I launched to kill and in the lot there is my unfortunate parent...
Quote:
I need to run these scripts, and they should never be allowed kill the parent. Is this possible do you think from the parents point of view?
Difficult because same UID...
But Perderabo gave you the workaround (a new subshell who becomes now the parent...).

service(8)						      System Manager's Manual							service(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
       directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT.  The  supported  values  of  COMMAND  depend  on  the
       invoked	script,  service  passes  COMMAND and OPTIONS it to the init script unmodified.  All scripts should support at least the start and
       stop commands.  As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the  start
       command.

       service --status-all runs all init scripts, in alphabetical order, with the status command.

       If the init script file does not exist, the script tries to use legacy actions.	If there is no suitable legacy action found and COMMAND is
       one of actions specified in LSB Core Specification, input is redirected to the systemctl.  Otherwise the command fails with return code 2.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

ENVIRONMENT

       LANG, TERM
	      The only environment variables passed to the init scripts.

SEE ALSO

       chkconfig(8), ntsysv(8), systemd(1), systemctl(8), systemd.service(5)
