Виснет бесконечный php-скрипт при работе с сокетами

[lk1918]

Добрый день!
Создал веб-сервер в виде связки nginx+apache+php-fpm. У меня есть бесконечный php-скрипт, который рассылает данные десктопным приложениям через сокеты. Однако, этот скрипт работает некоторое время и зависает. Грешу на неоптимальные настройки. Не могу понять, куда копать.
P.S. Прошу сильно не пинать ногами, ибо я новичок в администрировании дебиана

Для начала скрипт и php.ini под спойлер.

Пробовали локализовать проблему - найти кусок кода, который подвешивает скрипт?
Этот скрипт стоял на другой ОС и работал?
Сообщение объединено: 10 марта 2015, 14:37:09
Ну или профайлером посмотреть... куда что утекло...

[lk1918]

Благодарю за ссылки. Поставил профайлер, буду смотреть.
Еще один вопрос. Обнаружил в syslog:

И так повторяется периодически. Я правильно понимаю, что в кроне висят задачи по убиванию сессий?
И не может ли это влиять на подобную проблему?
