Java Openshift应用程序无法启动

我已将JavaEE应用程序部署到Openshift。它是根据示例创建并修改的。我部署了应用程序，工作正常，然后我更改了3个css文件，并将其推送到Openshift，但从那时起应用程序就不再运行了。我尝试重新启动（有时告诉我无法重新启动，有时重新启动），但没有结果-应用程序显示空白页或503错误。有什么问题吗？在我的本地系统上，应用程序运行良好，使用MySQL数据库。MySQL在Openshif上运行，我可以连接到它

网址：

如何从Openshift下载一些日志文件以查看？或者是什么原因，而在更改之前（只有3个css文件更改），一切都很顺利

最后我设法下载了服务器日志，我发现内存不足错误

谢谢。

如果您的内存不足，您需要使用较大的档位，您是使用较小的档位吗？Java可以很快消耗掉512MB的ram，特别是如果你在同一个设备上运行数据库，你也可以做一个扩展应用程序并将数据库放在自己的设备上，这可能会帮助一些人…

尝试使用rhc tail命令查看日志，或者使用ssh进入设备并查看~/app root/logs目录，然后在原始问题中发布您的错误谢谢您的回复，我添加了一些日志，我认为最有趣的是最后一个单服务器日志。我可以看到我的内存不足，“无法创建新的本机线程”。我理解，但听起来很奇怪。我有小齿轮和MYSQL数据库。但使用spring的应用程序非常小（可能有10-15个类和5个JSP），数据库有三个表，其中只有几行。另一个非常类似的应用程序运行良好……您可以尝试找到一个好的java评测工具，并在两个程序上运行它，看看它们使用了多少内存。
