Sounds about right - and I believe I did run into that once or twice (several eons ago) when I was in a purely java environment.
Interesting it had been set to the CF default - unless it was a newer server that FRIT setup. Whenever I updated the JVM I pointed CF to a different directory and the default JVM setup is to not cache indefinitely. Of course, FRIT may not have liked how I setup the servers and changed it :) Glad to hear it was resolved!
