Event in pending state - error finding DS object

Have a policy applied to a container with over 4000 user objects. Was applying the policy and some 24 objects are pending. The details on the event show:
Last Error as 15: Directory Services object could not be found.
I assume it is talking about the user object. I can see and manage the object in iManager and can search for it and see it in iMonitor. The object seems fine

Here are the details of the event.... Not sure why last attempt time shows as 1969
