Cascade Email Queue Processing Halted
Email notifications are not being sent after Cascade modified the email queue processing. Emails remain stuck in the queue indefinitely, and users don't receive important notifications like fix approvals or payment confirmations.
Cascade likely broke the async email worker or message consumer.
Error Messages You Might See
Common Causes
- Cascade removed @EnableAsync or @EnableScheduling from configuration
- Email consumer bean deleted or configuration modified
- Message queue serialization broken - messages can't be deserialized
- Cascade added exception in email processing that stops worker thread
How to Fix It
Ensure @EnableAsync is on configuration class and email sending is marked @Async. Check message queue (RabbitMQ, SQS, etc.) for messages. Review error logs for exceptions in email consumer. Test sending email manually to verify SMTP configuration. Monitor queue size and consumer status.
