--------------------------------------------
Summary: Credits never dropping to 0 when using multicast
addresses in senders connected to edge routers
Key: DISPATCH-1188
URL: https://issues.apache.org/jira/browse/DISPATCH-1188
Project: Qpid Dispatch
Issue Type: Bug
Components: Routing Engine
Reporter: Fernando Giorgetti
I have observed a strange behavior when exchanging multicast messages in a
topology with multiple interior/edge routers.
My topology is designed as:
[ Interior 1 ] -> [ Interior 2 ] -> [ Interior 3 ]
/\ /\ /\
[ Edge 1 ] [ Edge 2 ] [ Edge 3 ]
My manual test is attempting to perform the following:
* Connect a receiver to any of the routers and starts receiving from a
multicast address, like: "multicast.addr1"
* The receiver will close after receiving 1000 messages
* Next I am connecting a sender to any router and start sending messages to
that same multicast address, i.e.: "multicast.addr1"
* Sender will continue sending messages until credit drops to 0 (after
receiver has disconnected), then it will be closed
What I noticed was:
* If my receiver is connected to "Interior 1", received 1000 messages and
closed its connection, then senders connected to: "Interior 1", "Interior 2",
"Interior 3" or "Edge 1" will see credits dropping to zero
* But if the sender is connected to another edge router, like "Edge 2" or
"Edge 3", then credit never drops to zero (minimum I observed was 1)
Using anycast, credits are dropping to 0 across all routers in the network.
