Any idea how to get of the defuncts? #2

It seems that monit produces at least one defunct process by ps it monitors.

Any idea how to remove them and/or avoid that they are created?

I made a hack on how to get rid of defuncts processes, just chain supervisord and the monit in /etc/supervisord.conf:

[program:monit] command=/usr/bin/monit ; the program (relative uses PATH, can take args)

This is ugly but it works.

I also filed an issue on monit´s website:

What I do is to create monit.sh:

#!/usr/bin/env bash
monit -I -c $1

Then I just need to run monit.sh web-monit.conf. I can see that no defunct process created

What you need is a init for containers, for example, krallin/tini Dockerfile:

ENTRYPOINT ["/usr/bin/tini", "--"]
CMD ["/usr/bin/monit", "-I", "-c", "/etc/monitrc"]
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
