Answer 1

Sitecore.Publishing.HtmlCacheClearer.ClearCode() method (which logs this information) is executed every time the Publish execution is done (on local server or remotely).

It looks like your application executes Publish quite often. If you think this might be a bug, try to investigate which items are being published (e.g. by adding a hander to publish:itemProcessing event) and check what calls Publish for them.
