I've seen something similar on my laptop but I've never been able to repo it reliably.
Every once in a while JRun shoots to 100% CPU usage and my fans kick in and it stays there indefinitely until I kill the process. It seems to happen most often when waking the machine from sleep. It's a pretty rare occurrence so I've not looked into it too much, but perhaps Transfer's cache management thread has a bug in it. That'd explain why CF7 would work, since it doesn't use a separate thread.
