Gavin, Thank you. I know understand what was happening on my production machine. Why "some sort of echo?" In this case I was adding caching to my application. I had not used it before, so I placed an echo for "$auth cache created" into my code. During development I find it helpful. In this case, with a cache set to have a life of two hours, it threw me for a loop. Every once in a while (each time the cache needed to be refreshed) I ran into this error that I couldn't replicate, or at least that I couldn't replicate for another two hours. This isn't something I plan on doing in a production environment, so this solves my problem.
I'll haven't yet invested the time to learn about exception handling. This seems like something I'd throw into a log file rather then displaying on the screen.
