Stopping flocksnippet: Killed (core dumped) on doing kill -9

I am getting the following output of running a command on linux :
[robinsu@olympus101 ~]$ sudo service snippet stop

Stopping flocksnippet: Killed (core dumped)


Open in new window

Although my application does stop but i want to understand why this [FAILED] is coming. Is this something to be handled ?

Here is my init script used to stop and start the application:

# chkconfig: 3 99 99
# description: code snippet app
# processname: snippet


. /etc/init.d/functions

start() {
    FLOCK_APPS_CONFIG=$(cat /etc/env)
    exec="/usr/java/default/bin/java -DFLOCK_APPS_CONFIG=${FLOCK_APPS_CONFIG} -jar snippet.jar"
    cd $snippet
    daemon --user=$user $exec &
    [ $retval -eq 0 ] && touch $lockfile
    return $retval

stop() {
    echo -n $"Stopping $prog: "
    exec="pgrep -u flocksnippet | xargs kill -9"
    daemon --user=$user $exec
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval


case "$1" in
       exit 2
exit $?

You are killing the application instead of stopping it. The -9 signal you send it will trigger the application core dump as well as the text you're seeing. Try to reproduce by starting your application using the service start command and then killing that java command line (once running) using "kill -9 <pid>" where pid is the process id of that java command line.

If you want to stop the process you could leave out the -9 in the 'stop' command, like this:

exec="pgrep -u flocksnippet | xargs kill"

I see you're using daemon to start your process but you're killing all processes of user flocksnippet (pgrep -u) - I don't think this is the right way to stop your daemon process. I would just kill that java process (without the -9 still). How did you create / get your init script exactly?
Rohit BajajAuthor Commented:
I created the init script...
The daemon function which i am using is inside /etc/init.d/functions
There are no other process for the user flocksnippet.
My initscript is only createing process for this particular user

functions file you can look at :
Its same as i have on my linux machine

I can remove the -9 .. But since still this error happens i guess there must be something wrong with the way i am killing using daemon
