我的应用程序的所有版本突然停止工作。
类似于无法加载多个版本的AppEngine项目并看到HardDeadLineExceeded异常

12:28:59.323处理此请求的进程遇到问题，导致其退出。这可能会导致对应用程序的下一个请求使用一个新进程。如果经常看到此消息，则可能在应用程序初始化期间抛出异常。(错误码104)
这可能是由于应用程序启动时间过长造成的。当您的应用程序仍在初始化自身时，它超过了每个请求的硬性时间限制(30秒，但实际上显然更像是60秒)。
我也看到过这些情况，我认为这是你的应用加载成本太高，以及AppEngine方面出了问题;加载类所花费的时间似乎比预期的要长得多。因此，要么尝试精简你的应用程序，要么等待谷歌解决潜在的问题。
来自com.google.inject.internal.util.$FinalizableReferenceQueue$SystemLoader loadFinalizer的日志消息是转移注意力的，它们在AppEngine上使用Guice时是正常的，不应该造成伤害。
