Container does not stop

[priols]

Hi,
It sometimes occurs that a container does not properly stop. When I take a look inside the container at the running processes, I can see that there is a "sleep 1" which comes from the script /tmp/init.sh.
`#!/usr/bin/env sh

set -uxe

export CONFIG="/tmp/config.sh"
while [ ! -f "$CONFIG" ]; do
echo "No config, sleeping for 1 second"
sleep 1
done

echo "Found config file"
`

The configuration file is apparently not created in /tmp and the container is indeed stopped after creating a config.sh file in /tmp. Do you have any idea how it can occur?
