Expected Results
Outgoing mail continue to send out while Group Filter Subscription is processing the mails to be added in the Mail queue
Actual Results
Mail queue is stuck, no outgoing mail is send. Manually flushing mail queue does not work.
Notes
Filter Subscription that will generate the mails for each users will obtain a lock on the Mail queue on MailQueueImpl#addItem. The mail sender couldn't take lock for MailQueueImpl#sendBuffer to send those mails that already in the Mail queue due to it being locked by Filter subscription.
Workaround
Depending on use-case:
- Set Group Filter Subscription to use a group that has a smaller user count <200 users.
- Create a mailing list in Mail Server to be configured for the Filter Subscription. Create a dummy user in JIRA to be assign with the mailing list and the user will be the one subscribing to the Filter Subscription. Users who should be receiving mail subscription needs to be part of the mailing list.
