>          Issue Type: Bug

> *Scenario*
> * There are two Artemis brokers configured to form cluster
> * There is a producer sending messages to broker 1 and receiver receiving messages from broker 2
> * Between the brokers there is a proxy which simulates network failure
> * The proxy is several times stopped and restarted to simulate the network failure
> * The test expects that all messages sent to broker 1 will be received by receiver from broker 2 (despite the network failures)
> *Reality:* After the proxy is stopped and restarted, the cluster is not able to form again. Both brokers try to reconnect to their opposites but with no luck.
> *Customer scenario:* Messaging cluster is not able to recover after network failures.
> *Investigation of issue*
> I investigated why brokers are not able to reconnect and I found out that always when they try to reconnect, they give it up because there is no topology record for {{nodeId}} where they try to connect. So the re-connection attempt ends here \[1\].
> I compared the behavior with Artemis 1.x and I found out that Artemis 2.x removes the topology member when connection failure is detected, but Artemis 1.x doesn't. When I commented the line \[2\] it fixed the issue. This line is not present in 1.x.
