You will see this message exactly once (per node) if a node is restarted, in which case it can be safely ignored. But if it is logged continuously it means you really do have more than one node on the same network active concurrently with the same node id. This could occur if you have a backup node active at the same time as its live node.
This log message looks a bit specific to HornetQ. I'll move this thread there. Someone there might be able to answer.
Ok please do, im not even sure where should i post this, thanks for the help moving it to the right place
The same question on jboss-6.0.0.Final.
I had this same issue earlier today. You likely copied the entire "all" server directory after you had already started it once which causes the data directory to be copied over as well. This causes both nodes to start up with the same server ID sa HornetQ saves it's bindings there. If you don't have anything in the data directory you need (ie. you can go back to a fresh config) I solved this by deleting the data directory for both nodes.
Well, I actually deleted the data, log, and tmp and work directories to make absolutely sure I had a fresh setup, but I'm pretty sure it's only the data one you need to worry about.
You probably copied the journal files between two different nodes.
The serverID is now dynamically generated, with an UUID at the first time the server is started. (I mean with an empty journal)
if you started the server, then cloned the server, the same UUID will be applied to the cloned server and hence you will start to see errors.
You should probably cleanup the data files.
Thank you, Clebert. It works right now.
