When a Condor daemon shuts down, it sends a message to the central
manager asking it to remove the ad for that daemon. Sometimes those updates
get lost or dropped. Ads are removed from the collector after 15 minutes,
so even if the delete request is missed, when no new updates arrive the
old ad will be dropped.
