В логах апача child process still did not exit, sending a SIGTERM

Freebsd 9.1

Apache 2.2.25 + Nginx 1.4.3

Подскажите кто знает, чего не хватает апачу?

При его перезапуске

/usr/local/etc/rc.d/apache22 restart в лог сыпется много сообщений типа:

Может чего-то стоит убрать или добавить?

Спасибо за советы.
