Broker Quorum Lost

Symptom

Broker quorum is lost. This can happen if the number of running brokers falls into a minority number when compared to the total number of brokers that were established in the domain. See About Broker Quorum.

Cause

One or more broker processes are either shutdown, have failed, or have become unreachable (possibly due to hardware or network failures) which results in a minority number of brokers running.

Solution

Re-establish broker quorum using NuoDB Agent Tool.
