我有一个运行在glassfish 4.1.1服务器上的JSF 2.2 spring 4.x。
服务器由apache 2.4代理，它通过ajp协议向glassfish发送所有请求。
AJP监听器映射到线程池，最小线程数为50，最多线程数为150。
最近我注意到，当登录应用程序的用户数量达到〜100或更多时，虽然应用程序服务器或数据库服务器上的负载不大，但应用程序响应缓慢。
该服务器上运行VisualVM的我已经注意到了很多的150个AJP线程大部分时间封闭类似：在glassfish上运行的jsf应用程序上被阻塞的线程4.1.1

Locked ownable synchronizers:

的东西可能会导致任何想法？
PS。我在网上发现了一个类似的话题，那里的问题是javax.faces.PROJECT_STAGE没有设置为生产，但在这种情况下是这样。
更新：
我已经更新了Mojara从2.2.12到2.2.13，我仍然看到很多被阻塞的线程，但它似乎应用程序移动比2.2.12更好。
这是奇怪... 0刷新时段应该不会阻塞线程，虽然，它可能是你认为他们陷入了困境，但只是磁盘IO相对昂贵。禁用你可以将它设置为-1 btw ... – Kukeltje
大多数线程在visualVM中被标记为红色。 （“ajp-listener（89）” - 线程t @ 3357 java.lang.Thread.State：BLOCKED at java.lang.ClassLoader.loadClass（ClassLoader.java:404） - 等待锁定<7c1a25e8>（a org。 glassfish.internal.api.DelegatingClassLoader）拥有......）我不想永久禁用，因为有些情况下我需要在生产环境中进行一些html更新而不重新部署应用程序。 –
好..那么他们确实好像被卡住了...... – Kukeltje
