【问题描述】：
我们使用具有 6 个实例的 JBoss 集群 (EAP 6.4.10)，并大量使用捆绑的 Infinispan 5.2.11 来处理不同的内存网格用例。然而，它们中的大多数是分布式缓存（实际上是复制）。我们还将分布式事务和 JMS 绑定到混合中的事务边界。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)。
Infinispan 的同步是通过使用 JGroups 3.2.13 的 UDP 多播完成的
有时，尤其是在重负载下或之后，我们会遇到 JBoss 工作线程堆积在看似永远不会被释放的特定 Infinispan 内部锁上的问题。因此，http 连接池饥饿，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同一数据库的所有其他系统（它们是集群中的其他 JBoss 实例）。
目前我们观察 http 线程池，一旦线程开始堆积一定时间，实例就会从负载均衡器中移除并关闭。
有时这是不必要的，即集群会自行修复，并且罪魁祸首实例在没有人工干预的情况下再次开始正常运行。
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再次形成正确的 infinispan 集群。
来自挂起实例的堆栈跟踪总是显示几个有趣的特性：
-
一组线程（http worker）堆积在 JGroup 的流控制实现深处的一个条件上；在这些情况下，应用程序的最后一次调用通常是对分布式缓存的一些操作（例如

0x0000000374059958) 阻塞了数百个具有不同堆栈跟踪的线程；不过，它们都共享对某个分布式缓存的调用。 -
另一组线程（似乎是 UDP 协议处理程序，我们有一大堆）也是对象上的
awaiting notification。上下文似乎与 Infinispan 集群中的状态转移有关：Incoming-8,shared=udp awaiting notification on [ 0x00000003810b5188 ] at java.lang.Object.wait(Native Method) at java.lang.Object.wait(Object.java:502) at org.infinispan.statetransfer.StateTransferLockImpl.waitForTransactionData(StateTransferLockImpl.java:100) at org.infinispan.statetransfer.StateTransferInterceptor.updateTopologyIdAndWaitForTransactionData(StateTransferInterceptor.java:311) at org.infinispan.statetransfer.StateTransferInterceptor.handleTopologyAffectedCommand(StateTransferInterceptor.java:281) at org.infinispan.statetransfer.StateTransferInterceptor.handleNonTxWriteCommand(StateTransferInterceptor.java:222) at org.infinispan.statetransfer.StateTransferInterceptor.visitPutKeyValueCommand(StateTransferInterceptor.java:156) at org.infinispan.commands.write.PutKeyValueCommand.acceptVisitor(PutKeyValueCommand.java:82) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:120) at org.infinispan.interceptors.InvocationContextInterceptor.handleAll(InvocationContextInterceptor.java:128) at org.infinispan.interceptors.InvocationContextInterceptor.handleDefault(InvocationContextInterceptor.java:92) at org.infinispan.commands.AbstractVisitor.visitPutKeyValueCommand(AbstractVisitor.java:62) at org.infinispan.commands.write.PutKeyValueCommand.acceptVisitor(PutKeyValueCommand.java:82) at org.infinispan.interceptors.InterceptorChain.invoke(InterceptorChain.java:343) at org.infinispan.commands.remote.BaseRpcInvokingCommand.processVisitableCommand(BaseRpcInvokingCommand.java:61) at org.infinispan.commands.remote.SingleRpcCommand.perform(SingleRpcCommand.java:70) at org.infinispan.remoting.InboundInvocationHandlerImpl.handleInternal(InboundInvocationHandlerImpl.java:100) at org.infinispan.remoting.InboundInvocationHandlerImpl.handleWithWaitForBlocks(InboundInvocationHandlerImpl.java:121) at org.infinispan.remoting.InboundInvocationHandlerImpl.handle(InboundInvocationHandlerImpl.java:85) at org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher.executeCommandFromLocalCluster(CommandAwareRpcDispatcher.java:247) at org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher.handle(CommandAwareRpcDispatcher.java:220) at org.jgroups.blocks.RequestCorrelator.handleRequest(RequestCorrelator.java:484) at org.jgroups.blocks.RequestCorrelator.receiveMessage(RequestCorrelator.java:391) at org.jgroups.blocks.RequestCorrelator.receive(RequestCorrelator.java:249) at org.jgroups.blocks.MessageDispatcher$ProtocolAdapter.up(MessageDispatcher.java:600) at org.jgroups.blocks.mux.MuxUpHandler.up(MuxUpHandler.java:130) at org.jgroups.JChannel.up(JChannel.java:707) at org.jgroups.stack.ProtocolStack.up(ProtocolStack.java:1025) at org.jgroups.protocols.RSVP.up(RSVP.java:188) at org.jgroups.protocols.FRAG2.up(FRAG2.java:182) at org.jgroups.protocols.FlowControl.up(FlowControl.java:400) at org.jgroups.protocols.FlowControl.up(FlowControl.java:418) at org.jgroups.protocols.pbcast.GMS.up(GMS.java:897) at org.jgroups.protocols.pbcast.STABLE.up(STABLE.java:247) at org.jgroups.protocols.UNICAST2.up(UNICAST2.java:453) at org.jgroups.protocols.pbcast.NAKACK.handleMessage(NAKACK.java:793) at org.jgroups.protocols.pbcast.NAKACK.up(NAKACK.java:609) at org.jgroups.protocols.VERIFY_SUSPECT.up(VERIFY_SUSPECT.java:147) at org.jgroups.protocols.FD.up(FD.java:253) at org.jgroups.protocols.FD_SOCK.up(FD_SOCK.java:288) at org.jgroups.protocols.MERGE3.up(MERGE3.java:290) at org.jgroups.protocols.Discovery.up(Discovery.java:359) at org.jgroups.protocols.TP$ProtocolAdapter.up(TP.java:2616) at org.jgroups.protocols.TP.passMessageUp(TP.java:1269) at org.jgroups.protocols.TP$IncomingPacket.handleMyMessage(TP.java:1831) at org.jgroups.protocols.TP$IncomingPacket.run(TP.java:1804) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)只有 4 个线程在等待这个通知。

还有线程在等待一个锁，该锁由等待 (1) 中的条件的线程持有：

0x0000000507058c88，而后者又等待0x0000000374059958
关于我可以从系统中读取的内容，这就是它。里面严重卡了东西，但我不知道如何分析或排除故障，更不用说解决问题了。 （我们尝试更新到 EAP 6.4.20，但在此处可以观察到相同的行为，因此我们回滚了此更新，因为更新后出现了其他更新、更闪亮的问题。
我很乐意提供有助于诊断问题的更多信息（如特定配置参数）。
感谢任何人的帮助！
最好的，
马库斯
【问题讨论】：
-
不建议将捆绑的 Infinispan 实例用于您的用途。如果您在应用程序中捆绑 Infinispan 和 JGroups 版本，则可以更轻松地升级这些部分，而不依赖于基本 EAP/Wildfly 版本。我建议你转向这样的设置。最新的 Infinispan 版本是 9.4.0.Final。
-
@GalderZamarreño 感谢您的提示。目前，我们将大约 40 个工件（WAR 文件）部署到 EAP 实例，我担心在一台服务器上以某种方式运行 40 多个 infinispan 实例有点矫枉过正。另外，我们 AFAIK 无法使用 EAP 配置将缓存注入应用程序模块。另外，我了解red.ht/2kDmQ53 它实际上应该可以工作，或者作为设置没有那么牵强。除此之外，还有什么其他的吗？一个“受支持”的设置可能不会破坏我们使用 infinispan 的 40 多个模块？
-
一种选择是将状态推出 EAP 并将其放入 Infinispan 服务器实例。您可以在那里为每个 WAR 文件设置不同的缓存。
