After not taking any action, this error has stopped but has been replaced with

[26/Sep/2016:15:54:54 -0500] NSMMReplicationPlugin - agmt="cn=meToipa03" 
(ipa03:389): Missing data encountered
[26/Sep/2016:15:54:54 -0500] NSMMReplicationPlugin - agmt="cn=meToipa03" 
(ipa03:389): Incremental update failed and requires administrator action

for all of the replicas and things are slightly out of sync everywhere.  

Is the best course of action here to declare one a new master and do a 
ipa-replica-manage re-initialize to all of the others from that one?
