One of our agents forwarded in an email to the mailbox monitored by JIRA Service Desk to create a ticket, but one was never created. He re-forwarded in the same message again and this time the ticket was created very quickly by the system. So the same email, same content, sent in about 30 minutes apart. The first time a ticket didn't get created, and the second time it did. Is there any log I can check or other investigation I can do into why this might have occurred? We cannot afford to have someone monitor the email box to make sure JIRA is always creating a ticket, we have to be able to just trust that it is.
Edit 5/17/17 - This has happened again this morning. Nothing in the connectivity log or processing log indicates a problem from the inbox, and other emails are being processed for creating tickets and adding comments to tickets. But there was an email that came in from an internal email that did not have a ticket created for it.
