Description

We have an intermittent failure when using a cluster
of 2 replicated nodes (both are live nodes).

In the logs, I have:

This AMQ221027 is a bit hard to read but it basically says that I have
a connection from server f94b61cc to server fe8b1275...
However I don't have a corresponding log to show that the bridge is
also connected from server fe8b1275to server f94b61cc

When the test passes, I do have a 2nd AMQ221027 in the opposite direction.

How can I check that a cluster is properly formed? And why is it not always the case?
