> Key: LOG4J2-149
> URL: https://issues.apache.org/jira/browse/LOG4J2-149
> Project: Log4j 2
> Issue Type: Bug
> Components: Appenders
> Affects Versions: 2.0-beta4
> Environment: N/A
> Reporter: Scott Severtson
> Assignee: Ralph Goers
> Fix For: 2.0-beta4
>
> Attachments: SMTPAppender-always-log-last-event.patch, SMTPManager-buffer-synchronization.patch
>
>
> If multiple error events are logged against the same SMTPAppender/Manager at the same time, one email will contain both error messages, while the second will be empty (no events).
> The original SMTPAppender patch included synchronization against the CyclicBuffer to prevent such simultaneous access from multiple threads. This appears to have been lost in the merge/refactor. Patch (to follow shortly) re-introduces synchronization against the CyclicBuffer in the narrowest possible scope.
