Stop the Journaling task. Delete and recreate the Journaling Mailbox Target(from the EV Admin Console). Start the task. Let me know how it goes.
I'm sorry. I stopped the journaling task and recreated the journaling mailbox target and it did not resolve the issue.
Does anyone else have anything else I can try to resolve this issue?
Get a dtrace of the journal task as it starts up (since it should be trying to process those message) and send it to support along with the subject of some of the items not being processed.
