infinispan和jgroups的不正确的合并视图

Question

我有一个numOwners = 2的3节点infinispan集群，当节点从网络断开连接并加入时，我遇到了集群视图的问题。以下是日志：

（来电-1，BrokerPE-0-28575）ISPN000094：收到新集群用于信道ISPN视图：[BrokerPE-0-28575 | 2] （3） [BrokerPE-0-28575 ，SEM03VVM-201-59385，SEM03VVM-202-33714]

以下是我的JGroups配置：

我使用的Infinispan 7.0。 2和jgroups 3.6.1版本。我尝试了很多配置，但没有任何工作。您的帮助将不胜感激。

[UPDATE]将以下属性设置为1以上后，情况正常：“internal_thread_pool.min_threads”。

Answer 1

所以为了简化，我们有

• 查看经纪人| 2 = {经纪人，201,202}
• 201叶，认为现在是经纪人| 3 = {经纪人，202}
• 然后在视图broker | 3和broker | 2之间出现合并，导致视图代理不正确| 4 = {broker，201}

我创建了[1]来调查这里发生了什么。首先，合并视图的子视图应该包括202作为子组协调员，但事实并非如此。

你能描述一下究竟发生了什么吗？这可以复制吗？这将是不错的有FD，FD_ALL，MERGE3和GMS跟踪级别日志...
