Magento system log filling up with CSS and JS debug messages

Question

My Magento log is filling up with inlcusions of JS and CSS files (400 mb in couple of days) - what can this be?

I don't recall putting in any debug statements ...

Quite annoying

Where to start looking (Magento 1.8.1)

Answer 1

You could throw a mageDebugBacktrace() into Mage.php's log function to see what is calling Mage::log. Wouldn't recommend it in a live environment, though.
