Supervisord appears to be running, but monitored programs aren't launched

I've got supervisord 3.0a8 installed from the system package on ubuntu 10.04 (64bit). The supervisor service appears to be running, but it's not launching the configured programs. Interestingly enough, this exact configuration is running on another system, and is working as expected.

The main config file looks like this:

; /etc/supervisor/supervisord.conf
[unix_http_server]
chmod=0700
file=/var/run/supervisor.sock

[supervisord]
logfile=/var/log/supervisor/supervisord.log
childlogdir=/var/log/supervisor
pidfile=/var/run/supervisord.pid

[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
serverurl=unix:///var/run/supervisor.sock

[include]
files = /etc/supervisor/conf.d/*.conf

A sample program config looks like this:

; /etc/supervisor/conf.d/sample.conf 
[program:sample]
directory=/opt/sample
command=/opt/sample/run.sh

Where, the /opt/sample/run.sh is:

#!/bin/bash

while true; do
    T=`date`
    echo "[$T] Running!" >> /var/log/sample.log
    sleep 1
done

And, here's some additional information regarding the running instance of supervisord:

Any help is greatly appreciated!

I would add

loglevel=debug

to [supervisord] section. It might help. It seems include doesn't work. supervisorctl status should display your script running.

This happens to me when I forget to sudo supervisorctl update.

Also, does /opt/sample/run.sh have the executable bit set?
