Went on vacation and set an inventory refresh task for a number of our staff machines. Some of the machines were not on, so I would expect the connected machines to be refreshed and the ghost server to time out after 20 minutes. I returned from vacation and found the task still running after 4 days. Was curious why this happened. I've seen this particular task in operation before and after the incident, and it completes in a timely manner.

A little illumination, please?
