ProcessFlow Email Notification Error

We're using PF Pro for requisition approvals. Lately, we've been having an issue with the email notifications failing to be sent. Here's what it shows in pflow.out:

And here's what the work unit activity logs shows:

Anyone seen this before? We have a case open with Lawson Support but so far they have not been able to solve this.
