(Debian?) sshd 5.1p1-2 bug?



A bug has already been submitted:
http://www.nabble.com/Bug-496017:-openssh-server:-Aftger-upgrade,-pairs-of-message-chattering-about-channel-input,-every-15-seconds-td19100760.html

ii openssh-server 1:5.1p1-2 secure shell server, an rshd replacement

But I was curious if anyone knew why/what was causing this?
