Heroku loguje FATAL SignalException: SIGTERM

Nie rozumiem, dlaczego otrzymuję ten wyjątek FATAL. Działa dobrze w localhost.Heroku loguje FATAL SignalException: SIGTERM

Rozumiem, że SIGTERM jest po prostu sygnałem do zakończenia programu i nie wierzę, że rozwiązaniem jest jego obsługa lub zignorowanie.

Kiedy patrzę na wdrożoną stronę internetową, wyświetla się ona jako biała strona. Jak mogę naprawić ten błąd, aby moja aplikacja mogła wyświetlać się normalnie?

Oto moje logi Heroku:

@MichaelSzyndel Widzę podobieństwo w pytaniu, ale nie wierzę, że to odpowiada na moje pytanie. Zastanawiam się, co zrobić, aby to naprawić, a nie tylko to, co to oznacza. Szukałem od jakiegoś czasu, ale nie jestem pewien, od czego zacząć zmiany w mojej aplikacji, a może nawet w ustawieniach heroku. – stecd

Z tego, co widzę i rozumiem, jak działa Heroku, jest to całkowicie normalne zachowanie. Jeśli chcesz pozbyć się błędu, sugerowałbym użycie "prawdziwego" serwera WWW, spójrz na dokumentację heroku https://devcenter.heroku.com/articles/getting-started-with-rails4#webserver –

Kiedy hamownia wyłącza się, na przykład jako część daily restart lub jako część sleeping lub nowej wersji (jak masz w swoim przykładzie) następnie Heroku ma zamknąć procesy uruchomione w dyno.

Czyni to, wysyłając SIGTERM do procesów.

Wyświetlane dzienniki są zgodne z tym zachowaniem.

Rzeczywiście, jeśli uruchomię lokalny serwer Webrick i wyłączę go za pomocą SIGTERM (kill -SIGTERM <pid>), zachowuje się dokładnie w ten sam sposób.

To jest rozwiązanie tego błędu. Rozwiązałem ten sam @MSU_Bulldog –

To działało dla mnie. Dzięki za tonę! –

Rozumiem, że może to rozwiązać problem niektórych osób. Ale dobrze byłoby mieć jakieś informacje o tym, dlaczego to działa. Czy ktoś mógłby, proszę, wyjaśnić? – luizrogeriocn
