Messages ending up in ASB Deadletter queue #238

Closed danielHalan closed 9 years ago

danielHalan commented 9 years ago

Noticed that a lot messages ends up in the ASB Deadletter queue after running up 10+ workers, some without any NSB Error.

The max delivery count on your queue is probably to low, it should be 6x max number of instances

Ok... due that each worker might try the messages, with internal retry counters? Maybe should have a central storage for how many instances are running and then adjust the ASB "MaxDeliveryCount" accordingly.

We are aware of this issue/inconvenience, and have a feature request open on the core that would allow the delegation of FLR (and other retry rules) to a specific transport. I don't have an eta on this yet, but it is on the planning. I assume upping the retry count resolved the issue for now and close the issue, if not feel free to reopen
