Ted Ross commented on DISPATCH-343:
-----------------------------------
Quick status on this issue:
The thing about this test that causes the problem is that it uses 2-ack
transfers. The messages are sent by the sender, acknowledged (but not settled)
by the receiver, then settled by the sender. However, since it is built on
Messenger with a limited windows size, sometimes the receiver will settle the
deliveries (presumably because the window is full). All of this should work
fine of course, but it exposes a bug in the lifecycle management of deliveries
in Dispatch Router. A fix for this is imminent.
If this is a blocker for your project, you can probably work around it by
switching away from 2-ack deliveries. They are probably not providing any
added value since Messenger doesn't support exactly-once delivery.
