                 Key: AMQNET-258
                 URL: https://issues.apache.org/activemq/browse/AMQNET-258
             Project: ActiveMQ .Net
          Issue Type: Bug
          Components: NMS
    Affects Versions: 1.3.0
         Environment: Client side Windows 2003, NMS 1.3.0.1959, ActiveMQ Client 
1.3.0.1965
Broker ActiveMQ 5.3.1-fuse-01-00, Redhat Linux 64 bit

So the issue is that I'm getting "Unknown response ID" errors in my NMS client 
log. I've attached the client as nms-client.zip and the log as nms-client.log. 
I was running this client on a Windows server 2003 system though any Windows 
box should do.

The client is connecting with a failover URI like

failover:(tcp://mendoza:61616?keepAlive=true&wireFormat.maxInactivityDuration=0,tcp://mendoza:61617?keepAlive=true&wireFormat.maxInactivityDuration=0)?initialReconnectDelay=100&randomize=false&timeout=15000

The mendoza Linux machine has two AMQ brokers in M/S mode running on different 
ports. Broker configs are attached. The M/S is set up using KahaDB pointing to 
a NFS share on another Linux box. FYI to mount the share on mendoza I ran the 
following (pedro is another Linux box):

sudo mount -o soft,intr,rsize=8192,wsize=8192 pedro:/local1 /mnt/pedro/local1

To get this whole set up running, you'll need to change over the brokerUri in 
the client Program.cs to whatever host you are using and change the brokers to 
point to whatever NFS share you have mounted. To reproduce the failure, I had 
this running overnight but could see failures much earlier when I started 
taking down one broker at a time to start the failover process. 

Let me know if you need any more info.
