We are facing problem with the cluster, we have three nodes in cluster. Either of the node which is not master broker oftenly hangs and restart of single node does not helps. We end of restarting whole cluster.
Any one have experinced or have any idea? Let me know if need more details.
What is the version of the broker (as shown in the broker log at startup) ? What does the broker logs show, any errors, warnings ? As the brokers are server processes, you would need give more information to describe what did you mean by "hang" ?
