Translating "Coldfusion-out.log"

Hello, everyone,

I'm trying to track down why my application is causing an error, and coldfusion-out.log isn't being as articulate as I would prefer.

Jul 15, 2015 12:09:38 PM Warning [app name] - {t '12:09:38'} - form - 172.xx.xx.xx - /components/TRC.cfc - method=requestCost - 1 -- Word Fault -- [[[ followed by a JSON string of a serialized form ]]]

What does "Word Fault" mean, and how does it apply?

V/r,

^_^
