> Project: ActiveMQ

> Components: Broker
> Affects Versions: 5.8.0
> Reporter: Gary Tully

>
> Attachments: NetworkBridgeRemoveInflightTest.java
>
>
> In a networkbridge, a demandSub tracks outstanding asyncRquests and waits for
> them to complete on removal such that the messages can be acked correctly
> when the send completes.
> If the send is blocked on pfc on the remote broker, it may not return for
> some time, which blocks other removals leaving messages stuck inflight to
> networked subscriptions.
> The wait ensures that a message send will not be a duplicate, but blocking
> for ever does not make sense, especially considering that removes are
> serialised.
> We need some openwire command that can cancel pending sends to sort out this
> case but even then we need to timeout at some stage in case the other end
> cannot respond.
