monit не запускает apache

Я запускаю Apache и пытаюсь контролировать его с помощью Monit. Кажется, что мониторинг работает нормально, но когда Apache не работает, Monit не может его запустить.

Monit обнаруживает, что он не работает, но команда запуска не работает.

Ниже приведена конфигурация монитора

check process httpd with pidfile /var/run/httpd.pid
start program = "/usr/bin/apachestart start"
stop program = "/etc/init.d/httpd stop"
if failed host 127.0.0.1 port 80
protocol http then restart
if 5 restarts within 5 cycles then timeout

Это относится к сценарию запуска Apache, который включает следующее:

# cat /usr/bin/apachestart
## start Apache with default settings
ulimit -l 256;
ulimit -s 56000;
/usr/sbin/apachectl start;

Этот сценарий устанавливает несколько параметров, которые кажутся необходимыми для этой конкретной настройки Apache / PHP. Отлично работает при запуске из командной строки от имени root, но, видимо, для Monit это как-то проблема.

При запуске monit в режиме отладки (запускается с "monit -Iv") я получаю следующее

Есть идеи, почему monit не может запустить Apache?
