Is the fix like we get error for the Data transaction and report the error. Later we detect that EP is error and we reconfigured it ?

You are sure the code actually got built and installed? I don't expect the "READ(10) error to go away", but it should recover more quikly, if I'm not mistaken, just to be clear. --HPS
