> Key: DISPATCH-820
> URL: https://issues.apache.org/jira/browse/DISPATCH-820
> Project: Qpid Dispatch
> Issue Type: Bug
> Affects Versions: 0.8.0
> Reporter: Gordon Sim
> Assignee: Ted Ross
> Fix For: 1.0.0
>
>
> (1) start two connected routers
> (2) connect to one and open a sending link to the managament agent on the
> other
> (3) kill that other router
> (4) wait for some time until the killed router is removed from the first
> router
> (5) detach the management link
> You now get a double delete of an address hash with something like the
> following:
> {noformat}
