debug : Protocol Unknown. WTF?

Maybe anybody knows what the problem can be in? After a couple of minutes, when trying to start server:
debug : Protocol Unknown . sid=13,type=19,size=66,acceptsize=5
debug : Protocol Unknown . sid=14,type=19,size=66,acceptsize=5
debug : Protocol Unknown . sid=15,type=19,size=66,acceptsize=5
debug : Protocol Unknown . sid=16,type=19,size=66,acceptsize=5
debug : Protocol Unknown . sid=17,type=19,size=66,acceptsize=5

and so on continuously...

Which service is producing it?

its strange but, a few hours ago it was after glinkd, just a little later after gs01 loaded, and now its gone, and i didn't change nothing >_<. What a hell, can't understand?
