how to shutdown a qpid broker running on a specific port
On linux it seems qpidd -quite will shutdown the broker running on port
5672 by default. If I have more than one brokers running on the same
machine, how can I shutdown them gracefully by using qpidd commonds?
Now I'm stopping them by using kill, but that seems causing some trouble
on the next start, during which it would complain the following error:
2009-jun-22 09:45:48 critical Daemon startup failed: Exchange already
exists: amq.direct (MessageStoreImpl.cpp:489)
2009-jun-22 09:45:48 critical Broker start-up failed: Daemon startup
failed: Exchange already exists: amq.direct (MessageStoreImpl.cpp:489)
Thanks in advance,
Shan

Specify the port in use, e.g. for 5673:
qpidd --quit --port 5673

That is also fine.

This is a separate issue. In a clustered broker, you currently have to
have an empty store for all but the first node in the cluster. This
should be addressed in a future release (it is fixed on trunk I believe
by moving the current store 'out the way' to a subfolder on startup if
the node is not the first in the cluster). For now, when restarting a
node, if it is not the first node in the cluster you have to do that
manually.
