Looking through my notes for this time, and every other time this is happened, it appears it always seems to co-incide with a cups reload / restart. should I file this as a bug for lpstat? the last time there was a reload was on the 13th. same date as the "zombie" lpstat's"
grep reload /var/log/cups/error_log
I [13/Nov/2012:10:08:12 -0500] Full reload is required.
