Missing boxes on send to *

We use Groupwise as out communication medium for important announcements. This week we noticed that it is skipping users when we address to *. Gets most of the users but seems to stop about 3/4 the way through, going alphabetical.

We are using 8.0.3 HP3 on a SuSE 10 SP3/OES2.0.2 SP2 server. We are upgrading to 2014 and SuSE 11 after budget passes.

Running a PO database Analyse/Fix now, the Validate on both the PO and Domain passed.

Anyone have any experience with this in the past.
