我们使用具有6个实例的JBoss集群（EAP 6.4.10），并将捆绑的Infinispan 5.2.11大量用于不同的内存网格用例。但是，大多数都是分布式缓存（实际上是 replicated ）。我们还混合了分布式事务和绑定到事务边界的JMS。后端是SQL Server 2016 Enterprise，即使在这里事务也可以跨越多个SQL Server实例和数据库（DTC）。
使用JGroups 3.2.13通过UDP多播完成Infinispan的同步
有时，尤其是在高负载下或之后，我们会遇到一个问题，即JBoss工作者线程堆积在似乎永远不会释放的特定Infinispan内部锁上。因此，http连接池将处于饥饿状态，数据库上的打开事务不会被提交或回滚； JMS消息丢失；我们在数据库上面临一堆锁，这些锁会影响连接到相同数据库（集群中的其他JBoss实例）的所有其他系统。
当前，我们观察http线程池，一旦线程开始堆积一定时间，该实例就会从负载均衡器中删除并关闭。
有时这是不必要的，例如，群集可以自行修复，而肇事者实例又可以在没有人工干预的情况下再次正常运行。
但是，通常唯一的方法是手动重新启动实例，并保持手指交叉以重新形成正确的infinispan群集。
来自挂起实例的堆栈跟踪始终显示出一些有趣的功能：
一组线程（http worker）堆积在JGroup的流控制实现内部的一个条件下；在这种情况下，应用程序最后一次调用通常是对分布式缓存（例如remove()）进行的某些操作：

（全栈跟踪只是为了给您完整的图片）。此示例中的条件（0x0000000374059958）阻塞具有不同堆栈跟踪的线程的数百个线程；不过，他们所有人都将呼叫共享到某个分布式缓存。
另一组线程（看似UDP协议处理程序，其中有很多）也位于对象上awaiting notification。 Infinispan集群中的上下文似乎与状态转移有关：

关于我可以从系统中读取的内容。某些东西严重卡在里面，但是我不知道如何分析或排除故障，更不用说解决问题了。 （我们尝试将更新更新到EAP 6.4.20，但是在这里可以观察到相同的行为，因此由于更新之后出现了其他更新的，更明亮的问题，因此我们将此更新回滚了。）
我将很乐意提供更多有助于诊断问题的信息（例如特定的配置参数）。
感谢任何帮助！
最佳，

原来，监视您的GC日志中是否有有趣的事件非常有意义... x_X
情况是，我们使用CMS造成了旧式碎片，Java虚拟机定期决定将应用程序服务器暂停最多45秒以进行碎片整理。
我们切换到G1，这些暂停以及Infinispan不同步也消失了。在过去的几个月中，此设置现在运行稳定。
