When running a deployed process, the PC that the Atom is instaled on went into sleep mode and took the Atom offline. When the Atom came back up, the process was hung. It shows 'processing' status in the Process Reporting but after several 'Cancel Process Execution' attempts in the Action menu, it still persists. The Atom is backup and attempts to re-start the process are met with the 'Process is already running' message. How can I force the stop of the hung process?
