We recently upgraded to JIRA 5.1.8 (on premise) and are setup to leverage JIRA as a Support Ticketing system.
After the upgrade, any inbound email with High Importance locks-up in JIRA. Any attempt to access that ticket causes the UI to just "spin" or "hang". The other issue we notice is that email issue creation stops.
We've had to setup and leverage the CLI utility to delete these "stuck" issues so that filters, gadgets, etc continue to work. We just manually re-create the issue from the origal email later. We also have to log into the inbox that is setup with the email handler and delete the offending email(s). Access to other issues is fine while the 'stuck' issue condition exists.
Has anyone run into this issue before? Are there ways to configure the email handler to correct this issue? Or, is this is a bug? Thanks!
