[PROBLEM] constant POLL cec messages

[namtih]

While trying to map some new buttons on my remote, I also saw the following message in the debug log:

Code:

14:53:54 T:2963207232   DEBUG: CecLogMessage - command 'POLL' was not acked by the controller
14:53:54 T:2963207232   DEBUG: CecLogMessage - >> POLL not sent
14:53:55 T:2963207232   DEBUG: CecLogMessage - << Recorder 1 (1) -> TV (0): POLL
14:53:55 T:2963207232   DEBUG: CecLogMessage - << 10

This message is written every second while I'm in the XBMC menus. While playing a file it stops.
I this critical or a normal behavior of CEC?
