爲什麼我的彈簧啓動應用首先失敗，然後突然在cloudfoundry啓動？

我們剛剛將我們的四款應用程序遷移到彈簧啓動1.4和3，三個運行正常。第四個是唯一一個使用WAR包裝幷包含JSP的人。這個有一個非常奇怪的行爲：我們推動它，然後自動失敗兩次啓動，然後當CF第三次啓動時它會啓動。有沒有人曾經聽說過這個？我真的沒有想法。爲什麼我的彈簧啓動應用首先失敗，然後突然在cloudfoundry啓動？

要清楚：我只推送應用程序，然後cloudfoundry負責所有其他事情。它試圖啓動應用程序四次，直到突然成功。我不會以任何其他方式停止或啓動應用程序。此外，同樣的事情發生時，我們停止和啓動通過CF GUI應用程序，而不做前推...
