I have a user that is having to sync all items every few syncs. They get this error on their phone:

"AirSAMStateMachine.c 3873 4Sync key invalid, cmd:4,status:4"

At the same time they get that I get an error in the mobility logs:

"2010-12-03 15:11:24.258 ERROR [CP WSGIServer Thread-19] [getItemEstimate:211] [userID:cn=******,ou=***,ou=*****,o=*****] [eventID:] [objectID:] [Sync] Invalid SyncKey folder SyncKey 1 device SyncKey 3"

Can anyone give me some ideas on how to resolve this problem?
