Jose,

On my Pi running JNOS, I have the line in /etc/inittab like this:

8:2345:respawn:/jnos/startnos

Thanks Bob for your help.
 
I disable the Respawn and run it from the shell.  
This afternoon tested it in the office and Jnos stay alive for 4 hours without 
exiting until I exit and went home.  At home now, the status command show 
is up for 2 hours, 19 minutes, and 30 sec.
 
Something is wrong with the way I automatically restart 
routine in case of crash.
 
In /etc/inittab added this line:
 
##Start Jnos on bootup and respawn it should it 
crash
JNOS:2345:respawn:/jnos/startnos
 
My startnos:

#!/bin/sh
# Script to invoke the Linux Jnos.  
Usage: dojnos [optional_args]
# User should edit definitions for jnosroot and 
autoexec, and edit the
# $local and $remote addresses, and $mtu value in the 
DIP script below:
#
rm -f /jnos/spool/mqueue/*.lck 2>/dev/null
rm -f 
/jnos/spool/mail/*.lck 2>/dev/null
#
exec /jnos/jnos -d /jnos -v 
</dev/tty8>/dev/tty8 2>&1
#

So maybe something wrong with tty8 or should I try another 
tty?
 
Or if there is another way to autostart Jnos in the 
RPI?
 
Now, that I monitor my log more frecuently to try to solve 
my problem.  I see that hackers are trying to hack into my 
Jnos.
