Question

我遇到一个问题，应用程序挂起，可能是由于Jetty线程被阻塞，但我不是100％肯定如何解释线程转储，如果正常观察到什么以及如何跳线接收器生命周期是。

这是我正在观察的线程转储的一个特定部分：

AFAIK，接受器的数量应该在1到1的CPU之间，所以我假设这是在4核CPU中运行，问题是，从码头的角度来看，其他接受器被阻止等待是正常的其他接受者资源？如果是的话，这个资源可能是什么？

我不是很喜欢Jetty，所以我真的不知道这是否正常，他们只是在等待他们转向参加传入连接，如果是这样，那么问题是在不同的地方，但我想丢弃码头部分。

顺便说一句，码头版本是7.5.4

有什么想法吗？

由于

Jetty多个接受器阻止等待锁定和对象被其他接受器锁定
