Notifications are not sent to Reporters and Request Participants until an application restart

Problem definition

No customer notifications are sent to Reporters and Request Participants.

Steps to reproduce the issue

N/A

Diagnosis

• JIRA notifications are sent as usual, only Service Desk notifications that are not sending.
• Mail queue and error queue are empty.
• No errors or exceptions in the logs indicating that the emails could not be sent.
• New entries in the AO_4E8AE6_NOTIF_BATCH_QUEUE database tables have no SENT_TIME, which means that the notifications are queued but not getting sent.

Workaround

Restart JIRA
