----------------------------------------
Summary: Communication Timeout on Commit & Failover can lead to
message loss
Key: ARTEMIS-1304
URL: https://issues.apache.org/jira/browse/ARTEMIS-1304
Project: ActiveMQ Artemis
Issue Type: Bug
Affects Versions: 2.1.0
Reporter: clebert suconic
Assignee: clebert suconic
Fix For: 2.2.0
There is a small window that if your server takes more than the call Timeout to
activate during a failover, the client will fail to commit with a communication
exception, and there won't be any rollbacks associated with the TX.
if the client doesn't treat the exception, the consumers may have a wrong
buffer on consumers and you may endup losing messages.
Workaround: always reconnect the session, or rollback after a failure... or set
the callTimeout > time your server would need to activate itself.
This is likely a minor issue, but I would rather fix it.
