Lucee 5.3.2.77 stops sending mail

Just want to give everyone a heads up… I’m running into an issue where Lucee 5.3.2.77 stops delivering email over AWS SMS until the server is restarted. I don’t know the cause, and it’s happened to me twice, affecting over 1K emails. The emails get stuck in the tasks queue and will never be delivered until a restart. Executing the tasks manually also does not work.

The ticket is here: https://luceeserver.atlassian.net/browse/LDEV-2561

Any help is greatly appreciated!
