请参见：您是否尝试升级到较新的Camel版本启动Camel时，出现了某种错误，之后它会自动关闭？但是您在日志等中看不到任何错误或StackTrace，这些fill使用者一直在尝试轮询，但他们无法，因为他们正在关闭。也许你可以试着减少你的驼峰应用程序，减少路线，看看你是否可以把它固定到一个特定的路线上，也许是一个使用了一些特殊组件的路线，这会在RHEL上造成问题。您还可以尝试附加Java远程调试器，查看是否可以在“停止服务”处设置断点，并查看哪些服务是最重要的last@ClausIbsen我能够通过评论所有路线并逐个添加它们来发现问题。显然，客户端为多个路由放置了相同的文件路径，并且只有在同时启动两个路由时才会显示错误。奇怪的是，所有这些错误都没有出现……是的，这很奇怪。那么，有26条路由，就有2条路由的文件路径冲突？这通常不应该是一个问题，但是您将有多个使用者竞争相同的文件。还有一点奇怪的是，它可以在其他操作系统上工作，但不能在RHEL上工作。文件使用者所做的一切就是创建一个java线程，并使用java.io.file API扫描文件。@ClausIbsen不，其他操作系统没有这个问题。客户端编辑了属性文件，更改了目录（在该RHEL上），导致目录冲突。这在任何操作系统中都会失败。然而，奇怪的是，它只在2条未注释的路由中显示错误。取消注释都会产生更多的冲突，但是没有记录具有相同用户端点的路由。谢谢您的建议，不是吗。我设法找到了克劳斯评论中描述的错误。
