Did you set up your instances through the cf admin as well? I've been hearing that that's not the best way to do it and it's better to do it through jrun admin... I'll try that and see if it fixes it...
I think it's obvious that there is some kind of error probably on this line in the CF source code: int code = (hash & 0x7fffffff) % keys.length; A modulus by 0 will cause the error we're seeing... They should probably be checking if keys.length is 0. But what would cause keys.length to be 0 in the first place? Can someone at adobe confirm whether this is a bug or not and perhaps suggest a workaround until a fix is implemented?
