Почему мой супервайзер создает много одинаковых процессов?

Config:

[program:aws-mysql]
command=ssh -NCf -L 13306:host1:3306 user@host2
directory=/var/www/ECAME
user=root
autorestart=true
exitcodes=0

статус:

           ... a lot of " ssh -NCf -L 13306:host2:3306 user@host2"

Итак, почему мой supervisord создать много одинаковых процессов? Я думаю, что должен быть только один ssh -NCf -L 13306:host2:3306 user@host2,
