[jira] [Commented] (DISPATCH-1237) large frame multicast can stall
receivers if one receiver closes its connection
[ https://issues.apache.org/jira/browse/DISPATCH-1237?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16734539#comment-16734539 ]
Ken Giusti commented on DISPATCH-1237:
--------------------------------------
The message is being marked 'discard' because the terminal disposition is being set to PN_RELEASED. The expected behavior for unsettled multicast is to set the terminal disposition to PN_ACCEPTED if the sent message was delivered to any client, as it is in this case.

> Key: DISPATCH-1237
> URL: https://issues.apache.org/jira/browse/DISPATCH-1237
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Router Node
> Environment: The attached patch updates the edge router test to reproduce this issue.
> NOTE WELL - you must have the fix for DISPATCH-1235 applied before running this test else the router will crash.
> Reporter: Ken Giusti
> Priority: Major
> Fix For: 1.5.0

> Attachments: test.patch

> Ran the following scenario on an edge router:
> 1 sender (not presettled)
> 3 receivers
> multicast
> large message
> If I have one of the receivers close its connection while in the middle of a multi frame transfer the router marks the message as "discard" and does not forward the remaining frames to the two remaining clients, thus stalling their links.
