Ted Ross resolved DISPATCH-505.
-------------------------------
Resolution: Fixed
The underlying problem was that credit was not replenished for unroutable
deliveries arriving on anonymous links. The HELLO messages were not the
problem, but control messages sent to a specific router were occasionally
unroutable due to in-process topology changes.
> Eventual loss of credit on inter-router control links when the topology
> changes

> Key: DISPATCH-505
> URL: https://issues.apache.org/jira/browse/DISPATCH-505
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Router Node
> Affects Versions: 0.6.1
> Reporter: Ted Ross
> Assignee: Ted Ross
> Priority: Critical
> Fix For: 0.7.0
>
>
> It was observed that in a network of routers, connectivity would be lost on
> some of the inter-router links after a number of days of operation. When
> this occurred, the control links displayed a large (and growing) number of
> undelivered messages outbound as though credit were exhausted on the link.
> Other links remain open and the AMQP heartbeats flow such that the connection
> is never closed due to inactivity. This suggests that the problem is
> isolated to the control links only.
> It is also observed that this problem only occurs when there is expiration of
> HELLOs causing topology changes.
