For example.... what is unresponsive.... does a parse of the FEE64 log files ( before doing anything ) reveal a panic that is new? Does a STOP of the Tape work ? Does a Toggle of the MERGE pause state work ? Thus it will be possible to say that ..... FEE # is always the one responsible for DAQ failure or by < ???? > or the MERGE has found < ??? > problem.
