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.
