JTAG Communication Failure on ARM7 not always the Code's Fault

I have seen this issue 3 times during my current development effort. I had always assumed that my code was doing something to disable the JTAG. This morning, I decided to confirm the fact. After recovering with the Flash Magic Utility, I loaded the same Hex file as was loaded when the issue occurred. My board came up and ran nominally. So, it is not always the code's fault.
