Is there are way to terminate WFs that are over so many days. These are really old workflows that are in process. As the WF has been purged it seems the only way to terminate them is to go into each one. I have loads so this is not practical.
If the item no longer exists that the workflow is running on you can use the NWAdmn tool to terminate the workflows. NWAdmin.exe -o SyncTerminatedWorkflows -url teamsiteurl [-preScan] [-verbose] [-confirm] [-showMissingItems] [-terminateDeletedItems
