Confused on where this is coming from?

I keep getting files dumped into my bad file area specifically from FSX_IMG. In looking at my MUTIL.LOG I discovered this line. Hwever, I have no such node listed in my node file. See Below clip, can anyone shed some light on this ?
Note the node number, I have no idea what this is.
