---------------------------------------
Resolution: Won't Fix
LevelDB is no long supported
> ActiveMQ cluster blocks indefinitely in the presence of partial network
> partition

> 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.
