В чем причина «No input file specified» через некоторое время успешной работы NGINX + PHP-FPM?

Больше года работает на ноутбуке и сервере связка nginx+php-fpm. Работает вполне eспешно, но с какого-то момента nginx начинает выдавать "No input file specified"
Раньше меня эта проблема не беспокоила, решалась перезапуском nginx и php-fpm. На сервере даже добавил этот перезапуск в cron. Теперь нагрузки возрасли и эта ошибка начала мешать.

Включи логи фпм
Если у ты не хостер, то стоит поставить себе process manager static нагрузить себя запросами и подобрать pm.max_children так чтоб на бд и фронт у тебя хватило памяти

Почитай, что тебе в дефолтном конфиге фпм пишут

; Error log file
; If it's set to "syslog", log is sent to syslogd instead of being written
; in a local file.
; Note: the default prefix is /var
; Default Value: log/php-fpm.log
error_log = /var/log/php5-fpm.log

; Log level
; Possible Values: alert, error, warning, notice, debug
; Default Value: notice
;log_level = notice


; Choose how the process manager will control the number of child processes.
; Possible Values:
;   static  - a fixed number (pm.max_children) of child processes;
;   dynamic - the number of child processes are set dynamically based on the
;             following directives. With this process management, there will be
;             always at least 1 children.
;             pm.max_children      - the maximum number of children that can
;                                    be alive at the same time.
;             pm.start_servers     - the number of children created on startup.
;             pm.min_spare_servers - the minimum number of children in 'idle'
;                                    state (waiting to process). If the number
;                                    of 'idle' processes is less than this
;                                    number then some children will be created.
;             pm.max_spare_servers - the maximum number of children in 'idle'
;                                    state (waiting to process). If the number
;                                    of 'idle' processes is greater than this
;                                    number then some children will be killed.
;  ondemand - no children are created at startup. Children will be forked when
;             new requests will connect. The following parameter are used:
;             pm.max_children           - the maximum number of children that
;                                         can be alive at the same time.
;             pm.process_idle_timeout   - The number of seconds after which
;                                         an idle process will be killed.
; Note: This value is mandatory.
