----------------------------
Summary: 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
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.
