I'm running coldfusion 8,0,1,195765 with Transfer 1.1. It's odd to
me that it's not happening every time. I'm wondering if it's some
kind of garbage collection issue? Like I said, it only seems to
happen in the context of executing from inside of a CFThread with a
reference to my TransferFactory in the application scope. That
shouldn't matter as far as I know, but I'm not sure what kind of gc
implications that might have.
Thanks!
