Input - loop() Error

I can not specifically make this happen. It happens about every 8-15 hours with no indication when it is going to happen. The daemon crashes with a runtime error as the first indication of an error in the log. The error starts everytime with a loop () error associated to varying inputs each time it begins. But which input it starts with is not constant. Below is the most recent error with daemon debug on. It continues to list this error over and over with different inputs. I am not sure what I am looking at, but I can dig further, or try different things with some direction. Thanks.
