Question

我使用Hazelcast 3.2.6作为Hibernate的二级缓存。群集有4个服务器，在DB上执行多个读取/更新/删除操作。它运行正常很长一段时间突然我看到所有尝试执行db操作的线程都被卡住了，以下是线程转储的摘录，没有打印异常。

   java.lang.Thread.State: TIMED_WAITING (on object monitor)
    at java.lang.Object.wait(Native Method)
    at com.hazelcast.spi.impl.BasicInvocation$InvocationFuture.pollResponse(BasicInvocation.java:767)
    - locked &lt;0x0000000665956110&gt; (a com.hazelcast.spi.impl.BasicInvocation$InvocationFuture)
    at com.hazelcast.spi.impl.BasicInvocation$InvocationFuture.waitForResponse(BasicInvocation.java:719)
    at com.hazelcast.spi.impl.BasicInvocation$InvocationFuture.get(BasicInvocation.java:697)
    at com.hazelcast.spi.impl.BasicInvocation$InvocationFuture.get(BasicInvocation.java:676)
    at com.hazelcast.spi.impl.BasicInvocation$InvocationFuture.getSafely(BasicInvocation.java:689)
    at com.hazelcast.concurrent.lock.LockProxySupport.lock(LockProxySupport.java:80)
    at com.hazelcast.concurrent.lock.LockProxySupport.lock(LockProxySupport.java:74)
    at com.hazelcast.concurrent.lock.LockProxy.lock(LockProxy.java:70)
    at com.xxx.database.ccsecure.persistance.impl.DataStore.get(DataStore.java:120)

Answer 1

显然调用没有得到结果。这意味着调用未来不会完成。最大的问题是：为什么操作无法响应其请求。

你知道它是哪种手术吗？

使用二级缓存时，Hazelcast卡在TIMED_WAITING中
