near the bottom, you will see more complete info, most especially there will be lines that read roughly The last several times the runtime was xxxx, xxxx, xxxx, xxxx this time it was yyyy Compare the xxxx's to the yyyy. If yyyy is vastly greater than xxxx, then you do have a problem. For instance, if xxxx numbers are running around 25000 and yyyy is 17000000, this is an enormous extra delay. From 25 microseconds to 17 MILLIseconds. I have seen this on one of my test machines that is not used to run an actual machine. I think it is due to an extra network card, and it is somewhat rare, and diesn't interfere with motor and drive testing.
