[etherlab-users] working counter error after long time running

[Richard Hacker]

That looks like timing issues. It could also be hardware, but since you 
say this happens after process start, I think this is not really relevant.

Try to figure out your jitter or even overruns. You could increase 
debugging level and try to figure out what the master says
