[Andrei P. <and...@kl...>]

correct me if I'm wrong but isn't the master supposed to send the Announce
message only once, at initialization time, and after that just send sync
and follow-up messages? I can see a lot of Announce Messages sent by the
master:

Announce Messages are send every 7-8 messages. Is this right?

Thanks,
Andrei
