Gerard Beutlet and I were looking at a problem where the FMS 17 server returned a 956 error regarding logging in with the Data API. I searched here and see several comments about this from back in 2010, but nothing current about FMS 17 and the Data API. He solved the problem by including a logout in the script so that the sessions doesn't stay open for the 15 minutes. Which solves the immediate problem. But my questions is, how many are too many Data API sessions before an error 956 is kicked back? Does anyone know what that number is?
