java - JBoss EAP 7.0.0 OutOfMemoryError: 超出 GC 开销限制

Question

我在 JBoss EAP 7.0.0 中部署 WAR 时遇到问题。这场战争基于一个 Spring 应用程序。

在部署和删除 WAR 3 或 4 次后，我收到 OutOfMemoryError 异常：

...

我使用 VisualVM 分析服务器中发生的情况，我意识到每次部署中加载的类的数量都增加了（没关系），但是当我删除应用程序时它并没有减少。

此外，线程的数量似乎每次都在增加，但从未减少在部署期间创建的相同数量的线程。

我真的不知道发生了什么。我在 Tomcat 8.5.24 中测试了相同的应用程序，但我从未收到此错误，这让我认为该错误不在我的应用程序中，但谁知道...

任何想法？谢谢！
