It means that the client is broken and either (1) doesn't perform the  
necessary local db cleanup when it receives a status code to reset  
it's collection(s) - iOS does this - or (2) sends a PING request  
before all collections have been initialized during the initial pairing.

The best way to fix is to recreate the account on the device. You  
could try simply disabling/re-enabling all collections on the device  
first if you want, but that doesn't usually work on iOS, as it  
stubbornly holds onto the internal state, even when it's asked not to.
