Debian 8 Nexus 3k Flowcontrol RX Paused

Hej,
mam nexusa 3000 "ożenionego" z kartą LR-LINK 2x10G na debianie 8.

Wszystko było dobrze do czasu. Zaobserwowałem że na cisco mam dużo RX paused. Zrobiony LACP/bonding 2x10G

mniej więcej zaczęło się tak dziać (przy okazji "zacina" ładowanie stron itp. )jak ruch wzrósł >1G, co ciekawsze mam zrobioną też agregacje na mikrotiku 2x1G i tam nie spotkałem się z czymś takim.
Jakieś sugestie? podpowiedź w którym kierunku szukać?
