The oactives counters for igc2:0:txq:[0-3] are > 0, but didn't increase during the last 12 hours. Same for the qdrops. But at this moment I'm getting about 1200 NTP requests per second, as I lowered the bandwith setting in the pool a bit (to avoid getting removed from the pool). At the moment, there seem to be no or very little packet loss. I will increase the setting temporarily and see what happens with the counters.

No idea, I can check this tomorrow morning. Maurice
