What > On a production instance running James 3.7.0 I have 2900 + IDLE listeners for > only 58 IMAP connections. Something is clearly wrong here! > See attached screenshot. > A code audit showed that the listener associated with IMAP IDLE is only > removed when the use inputs "DONE" to close the IDLE command. > If the connection is unexpectedly dropped then the listener is never removed! > This is even more critical that this keeps the UID-MSN mapping in memory > forver (!). > h3. The fix > This is fixed on master (upcoming 3.8.0) as we no longer put a distinct > registration for IMAP IDLE but reuse the connection for the Selected mailbox. > Selected mailbox is cleaned up upon disconnection, deselection etc.. so we > don't need to worry. > Also it puts less of a churn on RabbitMQ component as IDLE becomes > essentially a hook on the SelectedMailboxImpl listener. > I propose to backport this to 3.7.1... -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: server-dev-unsubscr...@james.apache.org For additional commands, e-mail: server-dev-h...@james.apache.org
