Nice tip MarcS. That is indeed better than the other workarounds.
Here, a quick script -- cleanup-upstart.sh -- that checks initctl list
for stalled processes and kills them:
#!/bin/sh
# vim: set ts=8 sw=4 sts=4 et ai tw=71:
upstart_spawn_and_stop() {
name=$1
pid=$2
pkill -xf 'sleep 11' && echo "killed old sleep process"
echo $((pid-2)) |
sudo tee /proc/sys/kernel/ns_last_pid >/dev/null &&
sh -c 'sleep 11 &'
sleeppid=`pgrep -xf 'sleep 11'`
if test "$sleeppid" != "$pid"; then
echo "looks like we did not get the right pid.."
return 1
fi
parentpid=`ps -o%P -p$pid | sed -e1d`
if test "$parentpid" -eq 1; then
echo "very well.. we've got a live pid"
else
echo "looks like it got the wrong parent.. started from X?"
return 1
fi
return 0
}
pkill -xf 'sleep 11' && echo "killed old sleep process"
initctl list | tac | while read line; do
procpid=`echo $line | awk '{print $4}'`
if ! test -d /proc/$procpid; then
procname=`echo $line | awk '{print $1}'`
echo "$procname:"
if upstart_spawn_and_stop $procname $procpid; then
initctl status $name
initctl stop $name # "Terminated"?
fi
fi
done

Title:
init: job stuck with expect fork/daemon when parent reaps child

Bug description:
Hi
Wrong use of the expect fork stanza can create job with status
job stop/killled, process nnn
without any process nnn running on the system.
As an example the following avahi.conf should have used
"expect daemon", but will instead create a stuck job.
stop on stopping dbus-system
respawn
expect fork
exec avahi-daemon -D
