I guess it is no problem normally, and the engine will work with normal
strength. My engine also shows this behaviour. What happens is, that the counter
for the nodes will overflow typically after about 4 billion nodes. When reaching
this number of nodes, it will start at zero again.

It is similar to the milage counter on your car. Perhaps it has 5 digits, and
after mile 99999 it will jump to zero again (it will "overflow"). If your car
also had a stop watch for the time you drive, it could show your average speed
by dividing miles through the hours on the watch. When you hit 100000 miles, the
average speed will hit zero. Still your car did not get slower really.

Dieter
