[rabbitmq-discuss] Rabbitmqctl issues

I note that in my startup script for rabbitmq, it specifically uses /bin/sh
to run the daemon. Now this may be a long shot, but sometimes using a
different shell can cause subtle havoc. If you run rabbit (and stop it)
specifically from within /bin/sh, does it make any difference? Does it work
better if you use the functions as shown below (assuming the paths are
correct)?

PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DAEMON=/usr/local/sbin/rabbitmq-multi
NODE_COUNT=1

start_rabbitmq () {
    su rabbitmq -s /bin/sh -c "$DAEMON start_all ${NODE_COUNT}" > /dev/null
&
}

stop_rabbitmq () {
    su rabbitmq -s /bin/sh -c "$DAEMON stop_all" > /dev/null &
}
