[jira] [Created] (IGNITE-8922) Discovery message delivery guarantee can be violated

Anton Vinogradov (Jira)
Denis Mekhanikov created IGNITE-8922:
----------------------------------------

             Summary: Discovery message delivery guarantee can be violated
                 Key: IGNITE-8922
                 URL: https://issues.apache.org/jira/browse/IGNITE-8922
             Project: Ignite
          Issue Type: Bug
            Reporter: Denis Mekhanikov
            Assignee: Denis Mekhanikov
         Attachments: PendingMessageResendTest.java

Under certain circumstances discovery messages may be delivered only to a part of nodes.

It happens because pending messages are not resent due to data inconsistency in {{ServerImpl#PendingMessages}} class. If {{discardId}} or {{customDiscardId}} point to a message, that is not present in the queue, then other messages will be skipped and won't be resent. It may happen, for example, when queue in {{PendingMessages}} is overflown.

PFA test, that reproduces this problem.
