How-to to stop bearerbox with a script and -parachute

Hi Kannel Developers,

We have been using -parachute to start Kannel (using /etc/init.d/kannel) to
add extra reliability as it was dropping, but then we can't stop Kannel
using a stop/start script.  It's running using the latest CVS on Centos.
Without the 
-parachute the script works perfectly and we want to thank Stephane Rosa for
the great script.

The reason for the problem is when Kannel starts, with the -parachute, it
also starts a watcher process to ensure if the child process crashes it will
restart them automatically. The stop/start script stops the main process
stored in bearerbox.pid, smsbox.pid and wapbox.pid but does not stop the
-parachute watcher for the bearerbox.  The smsbox does go down after a
while, but the bearerbox watcher does not stop and allow the bearerbox to
drop and so you can't re-start Kannel using the script and you need to
manually kill the pid.

I'm not sure if this is a bug in the -parachute option.

Any suggestions appreciated.

[root@www init.d]# ls /var/run/kannel/
bearerbox.pid  smsbox.pid  wapbox.pid
[root@www init.d]# cat /var/run/kannel/bearerbox.pid
10073
[root@www init.d]# cat /var/run/kannel/smsbox.pid
10110
[root@www init.d]# cat /var/run/kannel/wapbox.pid
10124
[root@www init.d]# service kannel status
bearerbox (pid 10074 10073) is running...
smsbox (pid 10111 10110) is running...
wapbox (pid 10125 10124) is running...
[root@www init.d]# service kannel stop
Shutting down Mobile Gateway cvs-20070901:                 [  OK  ]
[root@www init.d]# service kannel status
bearerbox (pid 10074) is running...
smsbox (pid 10111 10110) is running...
wapbox is stopped
[root@www init.d]# service kannel status
bearerbox (pid 10074) is running...
smsbox is stopped
wapbox is stopped

Requires manual intervention:
[root@www init.d]# kill -9 10074
[root@www init.d]# service kannel status
bearerbox is stopped
smsbox is stopped
wapbox is stopped
