Question

在注意到我的Web应用程序不再在生产服务器上运行后，我查看了tomcat日志（ catalina.out ）：

部署“循环”以以下消息开头：

Mar 26, 2018 5:00:45 PM org.apache.coyote.AbstractProtocol pause
INFO: Pausing ProtocolHandler ["http-bio-8080"]
Mar 26, 2018 5:00:46 PM org.apache.catalina.core.StandardService stopInternal
INFO: Stopping service Catalina

我尝试多次重启Tomcat和整个服务器但没有成功。你能想象这里出了什么问题吗？

Answer 1

已报告类似案例，解释为Memory Leak。

关于此提示忽略 PermGen 的警告，为什么不使用正确的选项？这可能解释了导致问题的内存不足。

Java HotSpot(TM) Client VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0

如果使用正确的选项（XX:MaxMetaspaceSize）后仍然存在此问题，请尝试为其提供更多内存。尝试了解更改了什么，然后您的应用程序无法再运行（数据库中的数据已更改？如何？）。如果您仍然要说服自己，请删除该应用程序并启动Tomcat而不使用任何Web应用程序。

Answer 2

...奇怪你能用其他服务器运行你的应用吗？如玻璃鱼或码头？我知道它没有回答你的问题，但是如果应用程序与上面提到的服务器一起工作，那么你的tomcat会遇到一些问题，但如果不能正常工作，那么你的代码就会遇到一些问题。

Java / Spring应用程序：Tomcat突然无法再部署了
