Any one know what would cause station ports to blow on a CICS KSU? A client had one go on his CICS some years ago and another one went recently. He says it's my fault because I was on site a few days before on other business and is now refusing to pay his bill for the service call. It would be nice to be able to explain to him what can cause this to happen. I have no explanation to offer at this time. Anyone have any thoughts on this?
