Robbie Gemmell created DISPATCH-341:
---------------------------------------
Summary: router did not respond to request to drain a
message-routed consumers link credit
Key: DISPATCH-341
URL: https://issues.apache.org/jira/browse/DISPATCH-341
Project: Qpid Dispatch
Issue Type: Bug
Affects Versions: 0.6.0
Environment: Qpid Dispatch 0.6.0 RC3
Qpid JMS 0.10.0-SNAPSHOT
Reporter: Robbie Gemmell
With a router using the provided default config (updated only to set
saslMechanisms to ANONYMOUS), and attaching a sender and receiver (using the
JMS client Sender and Receiver examples) to the address "queue" (so presumably
using messge routing), it could be seen that Dispatch didn't respond to
requests to drain the receivers link.
In one case, after receiving some messages, a 'drain requst' flow is issued,
but neither enough messages to use the credit (expected since no more were
sent) or a 'drain reponse' flow are received, just heartbeating back and forth.

In another case, after flowing some credit but not receiving any messages, a
'drain request' is issued, but neither enough messages to use the credit
(expected since none were sent) or a 'drain reponse' flow are received, just
heartbeating back and forth.
