Log File Error Messages

Folks,

I’ve got two R-Pi devices running Kodi 17.1 and Chorus 2.4.2

Generally it works fine but every so often one of the add-ons results in ‘One or more items failed to play, check log for more details’

My log files appear to continuously record errors even when I am not using any Kodi functions, just the main interface showing.

One both devices the messages shown below appears to show continuously and I am unable to narrow down the entry that relates to add-on failure.

Code:
08:38:07.384 T:2868618224   ERROR: OpenConnection - could not opening a connection to the CEC adapter
08:38:07.389 T:2877006832   ERROR: CecLogMessage - could not start CEC communications
08:38:17.390 T:2877006832   ERROR: CecLogMessage - RegisterLogicalAddress - vc_cec_set_logical_address(E) returned invalid arg (8)
08:38:17.391 T:2877006832   ERROR: CecLogMessage - Open - vc_cec could not be initialised
08:38:17.391 T:2877006832   ERROR: CecLogMessage - could not open a connection (try 1)
08:38:18.392 T:2877006832   ERROR: CecLogMessage - RegisterLogicalAddress - vc_cec_set_logical_address(E) returned invalid arg (8)
08:38:18.392 T:2877006832   ERROR: CecLogMessage - Open - vc_cec could not be initialised

I have not knowingly installed any non Kodi add-ons.

Is the above message a normal log function or have I got a problem?
