Anyone else having issues with PowerShell Activities getting "stuck" in progress?
Occasionally, PSAs will hang indefinitely in an "In Progress" state. As a workaround, we find the ones that have been in progress for over an hour and set the status to "Rerun" and they always successfully execute on a subsequent run, usually in less than a minute. I've found these two variations of errors in the PSA logs for the ones that get stuck in progress, and corresponding errors in the workflow server's windows application event log.
Unexpected Error 1: (most predominant for stuck PSAs) ======================================
3/28/2018 7:55:12 AM Invoke PowerShell Object

Unexpected Error 2: (less common, but also seen with stuck PSAs) ======================================

I do have a support ticket open with Cireson, just wanted to see if anyone else is experiencing this.
