Charles E. Rolke commented on DISPATCH-1554:
--------------------------------------------
Running this same test on Dispatch release 1.10 shows no issue with link state
costs. After the network stabilized then there were never any more ROUTER_LS
log lines issued during or after the barrage of link creations.
Also with 1.10 all 1000 addresses were propagated to all nodes in the network.
Note that the addresses were propagated to all nodes in the original test
yesterday as well.

> Key: DISPATCH-1554
> URL: https://issues.apache.org/jira/browse/DISPATCH-1554
> Project: Qpid Dispatch
> Issue Type: Improvement
> Components: Routing Engine
> Affects Versions: 1.10.0
> Reporter: Charles E. Rolke
> Priority: Major
>
> Four routers are connected in a linear network: A-B-C-D.
> A proton cpp client test program
> https://github.com/ChugR/qpid-proton/blob/cr-link-address-generator/cpp/examples/qdr_moad_recv.cpp
> opens 1000 receivers on router B.
> {{ qdr_moad_rcvr -b $INTB_normal -l 1024 -c 1000}}
> The barrage of receiver creations takes about 0.3 seconds. The router logs
> show:
> * within a few seconds all routers emit empty computed link cost values.
> * 25 seconds later costs are stable again
> * then costs are then propagated between A and B, and C and D only. A and B
> cannot see C and D, and vice versa
> * 15 seconds later costs are stable again
