Subject [jira] [Created] (AMQNET-415) Client overloads server with wrong credentials when using failover
Date Thu, 21 Feb 2013 19:00:13 GMT
Jim Gomes created AMQNET-415:

             Summary: Client overloads server with wrong credentials when using failover
                 Key: AMQNET-415
             Project: ActiveMQ .Net
          Issue Type: Bug
          Components: ActiveMQ, NMS
    Affects Versions: 1.5.6
         Environment: ActiveMQ Broker 5.6.0
            Reporter: Jim Gomes
            Assignee: Jim Gomes
            Priority: Minor
             Fix For: 1.5.7

If the ActiveMQ broker has been secured to enforce login credentials, the NMS client will
continually attempt to authenticate against it if it is using the failover protocol.

Steps to Reproduce:
1. Configure the broker to require login credentials for connections.
2. Configure the NMS client to use failover mode.
3. Configure the NMS client with incorrect login credentials.
4. Attempt to connect the NMS client to the server.

The client reattempts login continuously without backing off, and has a significant impact
on the performance of the server.

The client should exponentially back off in the same manner as it does when attempting to
reconnect to a down server.

This was experienced using the OpenWire client, but a similar bug may exist in the STOMP client's
failover code.
