> Key: AMQ-7064
> URL: https://issues.apache.org/jira/browse/AMQ-7064
> Project: ActiveMQ
> Issue Type: Bug
> Components: activemq-leveldb-store
> Affects Versions: 5.15.3
> Reporter: Network
> Priority: Major
>
> We set up a cluster of 3 ActiveMQ brokers (Replicated LevelDB Store). other 3 machines were used to run Zookeeper cluster. We configured ActiveMQ as the following:
> * Replicas: 3
> * sync: quorum_disk
> when a partial network partition isolates the master broker from the other brokers while ZooKeeper can communicate with both sides of the network partition, the cluster will block indefinitely and clients messages will not processed. The following are the steps to reproduce the behavior:
> # partial network partition such that the master broker will not be able to communicate with other brokers but can communicate with Zookeeper nodes (ZooKeeper nodes are reachable for all brokers)
> # a client sends a message. However, it does not receive a response. it seems that the cluster stopped processing client request.
