Hello Patrick,
the message seems to suggest that the consumer on the master closes
while there are still messages in the pre-fetch queue. Those messages
will be requeued.
I think this is exactly the bit of information I was looking for. :) I
just didn't know about the pre-fetching. The log lines were then created
because I'm closing the consumer after reading a single message.
Thanks a lot!
It is hard to tell why this is happening without knowing more about
how you are using JMS in your application.
How exactly are the workers reporting their results to the master?
Do they use the same queue or do they have separate queues?
Do you have a single consumer on the master or several consumers?
How, in your application, can the consumer(s) on the master be closed?
Also, may I ask which version of the Qpid client/broker you are using?
Kind regards,
Lorenz

Hello Qpid users,
I'm running the Qpid Java broker in a master-workers setup where a
master process continuously puts tasks into a queue which are then
processed by the workers. When finished a worker sends back its
result to the master and looks for new tasks to process. After
running a few minutes I realized that the master process logs an
increasing number of lines like this:
Received a message(1681529877)[1246] from queue consumer(341) is
closed rejecting(requeue)...
Unfortunately I could not find out what this actually means, i.e. if
this is a severe issue (it is logged as 'info' message), what could
have caused it and how to prevent it.
Can you give me some pointers?
Thanks in advance,
Patrick
