exit all supervisord processes if one exited - docker

Question

I have a docker image where I wish:
- to run a passenger server and another daemon for monitoring the passenger server.
- the container to exit as soon as either one of these 2 processes exit even once.
- direct all logs to stdout
In config file, I have put an event listener (Reference: https://serverfault.com/questions/760726/how-to-exit-all-supervisor-processes-if-one-exited-with-0-result/762406#762406) that captures some events for passenger_monit program and executes a script tt.sh.
I can see 1 extra instance of passenger_monit program being spawned and reaching FATAL state after a few tries. The other passenger_monit and passenger_server are fine. The other passenger_monit's events don't reach the eventlistener.
These are the scripts which are not working as expected:
This is the supervisord.conf
[supervisord]
nodaemon=true
stdout_logfile=/dev/fd/1
redirect_stderr=true
stdout_logfile_maxbytes=0
[unix_http_server]
file=%(here)s/supervisor.sock
[supervisorctl]
serverurl=unix://%(here)s/supervisor.sock
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
[program:passenger_monit]
command=./script/passenger_monit.sh
process_name=passenger_monit
startretries=999
redirect_stderr=true
stdout_logfile=/dev/fd/1
stdout_logfile_maxbytes=0
autorestart=true
killasgroup=true
stopasgroup=true
numprocs=1
[program:passenger_server]
command=passenger start

redirect_stderr=true

stdout_logfile_maxbytes=0

[eventlistener:passenger_monit_exit]
command=./tt.sh
process_name=passenger_monit
events=PROCESS_STATE_STARTING,PROCESS_STATE_EXITED,PROCESS_STATE_FATAL
stdout_logfile=/dev/fd/1
stdout_logfile_maxbytes=0
This is the ./script/passenger_monit.sh
#!/bin/bash
set -x
cd /passenger/newrelic_passenger_plugin/
# if exec is not put, then this process is not killed when supervisord exits
exec ./newrelic_passenger_agent
set +x
This is tt.sh
#!/bin/bash
echo "in tt!"
This is the command I run:
docker exec -it -u deploy 56bbbbe4352b supervisord
This is the output I get:

The following should work. Notice the 10 second script will be killed after 5 seconds.
[supervisord]
loglevel=warn
nodaemon=true
[program:hello]
command=bash -c "echo waiting 5 seconds . . . && sleep 5"
autorestart=false
numprocs=1
startsecs=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
[program:world]
command=bash -c "echo waiting 10 seconds . . . && sleep 10"
autorestart=false
numprocs=1
startsecs=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
[eventlistener:processes]
command=bash -c "echo READY && read line && kill -SIGQUIT $PPID"
events=PROCESS_STATE_STOPPED,PROCESS_STATE_EXITED,PROCESS_STATE_FATAL
