Charles E. Rolke created DISPATCH-1731:
------------------------------------------
Summary: Edge router counts all addr_lookup messages as delayed
Key: DISPATCH-1731
URL: https://issues.apache.org/jira/browse/DISPATCH-1731
Project: Qpid Dispatch
Issue Type: Bug
Components: Routing Engine
Affects Versions: 1.12.0
Reporter: Charles E. Rolke
A test network has 12 routers ( [^edge2-apr5-network-diagram.pdf] ), four
interior routers connected in a line, each with two edge routers.
A test runs sending unsettled multicast messages to EA2 and ED1, and receiving
them on INTA, EB1, and ED2. On top of that routers EC1 and EC2 have
intermittent receivers that continuously (connect, receive between 1 and 5
messages, disconnect). See attached png file.
The issue is that routers EC1 and EC2 show every message sent over link 14 as
_delayed_.

Note that edge addr lookups are happening at the rate of 5 to 10 lookups per
second as the test receivers connect and reconnect as fast as they can.
