我正在尝试在 dotcloud 上设置一个 twistd 守护进程：
我的 supervisord.conf 文件：
[program:apnsd]
command=/home/dotcloud/env/bin/twistd --logfile /var/log/supervisor/apnsd.log apnsd -c gp_config.py
directory=/home/dotcloud/current/apnsd
但是，它看起来像命令'exits early'，然后提示Supervisor尝试并重新启动，然后由于twistd dameon在后台运行而失败。
从supervisord日志：

This could either be a previously started instance of your application or a
different application entirely. To start a new one, either run it in some other
directory, or use the --pidfile and --logfile parameters to avoid clashes.

尝试通过包装脚本启动进程时（并使用 exec 以便不创建子进程）时，我遇到了类似的问题。我究竟做错了什么？
