I think you could be right but I don't know why it would stop working all of
the sudden. Like I said I'm continuing to research and every little bit I
get from the list here helps. Here is the outtake from my .cfg file for one
of the interfaces...


### Interface 21 >> Descr: 'Serial1/0.40' | Name: 'Se1/0.40' | Ip:

1) most cases are solved by showing folks a part of config file.

2) .log file will be *just* overwritten in normal case too.

3) isn't this a famous MaxBytes/AbsMax problem?

Your AbsMax may be 128000 since rateup called with '-z g 2023150802 
1196177688 128000 ', also it implies unknaszero and gauge.
When in-value(2023150802) is greater than max-value(128000), with 
unknaszero is set, it will be treated as 0.
Same rule apply to out-value calculation.


I'm not sure if I'm right :)
