[quote author="lesatglsi" date="1333903037"]I have googled and searched the forums and can't find any reference to something that seems basic - how to clear the logfile?
I tried just erasing it - it came back with all the content.[/quote]
it's most likely because you have your error logging to log all messages.
in your application/config/config.php file
find something like this and make it 0 instead of 4 or whatever number it is.
$config['log_threshold'] = 4;
