[B.A.T.M.A.N.] Can't create new originator

Hi.
I saw strange batman logs while testing a batman-adv mesh. Batman-adv module was continuously generating the same logs including a " Creating new originator: b0:c6:9b:80:01:43". But b0:c6:9b:80:01:43 never appears in the output of 'batctl o':
admin@HND-Mesh:~# batctl o

Now I can nerver reach b0:c6:9b:80:01:43. Anyone tell me why this happens?
And, what does "Drop packet: packet within seqno protection time" mean? What is the "seqno protection time"?
Any help will be appreciated and thanks in advance.
