docker stop timing out, sigterm ignored

[Youn-Perron]

Hello,
the issue I'm facing is I can't stop the container gracefully via docker stop. Every default termination signal (SIGTERM, SIGINT) seem to get completely ignored. Nothing about any signal being received appears in the logs either. The only way I've found to stop the container is to resort to SIGKILL, which does not ensure graceful termination.
Could there be something I'm missing, or is there no proper way to terminate the process except for killing it and praying for the best ?
Thanks a lot.
