Извините, если это кажется бессвязным. Я пытался устранить / решить эту проблему в течение последних 20 часов, при этом мне приходилось присматривать за сервером и перезапускать php5-fpm каждый раз, когда он выходит из строя.
Я предполагаю, что есть основная проблема с плагином (сайт WordPress с высоким трафиком) или чем-то, что подвешивает этот поток, что может вызвать блокировку зависимости, которая связывает другие потоки. Мое непосредственное беспокойство - найти способ заставить Emergency_restart_threshold автоматически перезапускать php5-fpm, когда это необходимо. Тогда я могу спать и найти основную проблему PHP. Проблема возникла 21 раз за последние 24 часа. Иногда с разницей в 3,5 часа, иногда всего пара минут.
Я экспериментировал с различными значениями времени, но пока ничего не запускает необходимый сигнал SIGSEGV или SIGBUS. Похоже, что как только проблема начинается, все запросы PHP зависают, как будто все они чего-то ждут, и 150 Max Children в конечном итоге заполняются входящими запросами, прежде чем различные тайм-ауты убивают их. За исключением случаев, когда возникает эта проблема, обычно для удовлетворения текущего трафика требуется всего 2-5 детей.
Сервер представляет собой Amazon EC2 c4.Xlarge (7,3 ГБ ОЗУ, 4 виртуальных процессора) под управлением Ubuntu 14.04.
У меня также установлен New Relic, и ресурсы кажутся очень хорошими. Доступно более половины памяти, а загрузка ЦП обычно значительно ниже 50%, за исключением случаев, когда PHP5-FPM зависает.

В нем много статей, но все они делятся на две категории, показанные ниже.
В FastCGI: comm with server "/var/www/cgi-bin/fastcgi.php5-fpm" aborted: read failed генерируются, когда я вручную перезапускаю php-fpm, когда он принудительно закрывает все соединения, которые все еще открыты.
В stderr: Primary script unknown они вызваны тем, что боты пробуют случайные URL-адреса и вызывают ошибку 404.

У меня есть много других сохраненных журналов, а также подробные записи о различных попытках изменения конфигурации. Не был уверен, что еще может иметь отношение. С радостью размещу все, что могло бы помочь.
Спасибо за любые предложения по поиску решения. Даже если это временный обходной путь, поэтому я могу оставить сервер без присмотра достаточно долго, чтобы спать и подзарядиться.
