Subject [jira] Commented: (AMQNET-258) Getting Unknown Response ID errors in client log on failover
Date Fri, 25 Jun 2010 15:31:52 GMT


Timothy Bish commented on AMQNET-258:

Looking a bit deeper I'm not sure how feasible it is to remove these errors, it'd be a bit
of a hack.  In reality the java client will log the same errors from its response correlator
if you configure your such that the class detects
that debug logging is enabled for its logger.

>                 URL:
>             Project: ActiveMQ .Net
>          Issue Type: Bug
>          Components: NMS
>    Affects Versions: 1.3.0
>         Environment: Client side Windows 2003, NMS, ActiveMQ Client
> Broker ActiveMQ 5.3.1-fuse-01-00, Redhat Linux 64 bit
>            Reporter: Jonathan Anstey

> So the issue is that I'm getting "Unknown response ID" errors in my NMS client log. I've
attached the client as 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
> Let me know if you need any more info.
