Not sure what you mean? I cut and paste the logs so clearly
there is something happening i.e. a reason for those messages?

Yes, I think you are right ! Here is a cut from the conf file :-

# Buffering program - to help streaming
$buffer = 'buffer'; # one of false/buffer/mbuffer
$buffer_megs = '10'; # buffer memory size (in megabytes)
$buffer_fill_pct = '75'; # start writing when buffer this percent full

Unfortunatly not - the times are different so this could two
unrelated issues.

If you could indicate which information I would need would that help?

Any tips on how to do that ?
