Some further digging into this and I see that the changes this morning 
to at least one of these entries are not present in the accesslog 
database.  No wonder the change didn't make it to the replica's, it 
didn't even make it into the accesslog on the master (although auditlog 
sees the change and the dc=uvm,dc=edu database on the master has the 
change).

Any suggestions on where to look in the accesslog overlay to see why 
these modify operations are not being recorded?

Thanks,
