----------------------------------------
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.
