http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=15529 Bug ID: 15529 Summary: Process Message Queue may send duplicate emails if process is launched twice Change sponsored?: --- Product: Koha Version: master Hardware: All OS: All Status: NEW Severity: enhancement Priority: P5 - low Component: Notices Assignee: koha-bugs@lists.koha-community.org Reporter: barton@bywatersolutions.com QA Contact: testopia@bugs.koha-community.org Neither process_message_queue.pl nor C4::Letters::SendQueuedMessages have any method of ensuring that duplicate emails are not sent if two or more instances of process_message_queue.pl are running concurrently. This seems to have caused issues on a server which was re-running cron jobs because the system clock was re-set by NTP, but it could also cause issues if process_message_queue.pl took a very long time to process. -- You are receiving this mail because: You are watching all bug changes.
