Process Management Services- Processes not getting unarchived in distributed Environment

Hi,

We have the distributed Environment so we have Archived Folder on App Server, Now when we are using archived processes smart service, the process is getting archived but when we try to either find the process through PM UUID and Archive Date or we try to unarchive the process through ppid, it is not finding archived process.  Can anyone guide why this would be happening and how can we resolve it?

Thanks
