一段时间后Apache Ignite缓存冻结

Question

我有一个包含6个服务器和1个客户端节点的群集。我的客户端节点会进行大量更新并创建作业，并且还有一个过期策略以捕获过期的项目。

但是，每天，集群至少冻结一次。即使在通话过程中ignitevisor的缓存命令也会冻结。

所以我一直看着线程转储，我看到了一个奇怪的事情是，有一大把相同的语句是这样的：

"pub-#39%null%" #51 prio=5 os_prio=0 tid=0x00007f9788623800 nid=0x1d02 waiting on condition [0x00007f9769ddc000] 
    java.lang.Thread.State: WAITING (parking) 
    at sun.misc.Unsafe.park(Native Method) 
    - parking to wait for <0x00000006c004aaa8> (a java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject) 

所以有大量的等待状态的线程，但是好像从来没有发生。

我的缓存配置是这样的：

我真的需要帮助这里。 THX

这是在Apache点燃论坛讨论：http://apache-ignite-users.70518.x6.nabble.com/Apache-Ignite-cluster-freeze-after-a-period-of-time-td7726.html

最有可能的僵局被重新排序密钥的putAll操作中引起的。
