I have the same problem,And search the source. I guess is the limit on reliable out packets size,but i do not know why.
Fighting this issue right now as well. Not even sure if this comes from the server or the client.

Connection LostAs it turns out, a Bunch is created for an actor, containing (i gues) everything that needs to be send to the client. If that bunch is to big (> ~4000bytes) the Bunch is split into PartialBunches. If the following condition is met:
if (Bunch->bReliable && (NumOutRec + OutgoingBunches.Num() >= RELIABLE_BUFFER + Bunch->bClose))
you will receive that error.
RELIABLE_BUFFER = 256
Keep in mind that property data of an actor is always reliable.
