Y i will try it this way. There are some other problems : Some
connections catch CNC-Center and other mashine data all over the time.
So its not that easy at all. But i will try it with a commit on idle.
And Reconnect on that 24h connections. (They sleep most of the time so
it would be a better technic to terminate the connection and reconnect
all 5 mins. It will save resources too)
