Здравей, от много голяма полза ще бъде ако покажеш изхода от следните команди:
netstat -s
и
ethtool -S <interface>
тази команда за всяка лан карта, която ползваш.
и
ethtool -k <interface>
За всяка карта (това не е чак толкова важно, просто за информация).
Интересно ще е да наблюдаваш чрез ethtool -S картата, където имаш проблем докато се случва и да
се опиташ да забележиш дали някой от *_errors броячите се променя много/често по време на проблема
(e.g. watch ethtool -S <interface> за всяка карта докато се случва проблема)
Малко дългичко ще се получи, но ето:

Наблюдавал съм с ethtool като я има драмата, сравнявал съм параметрите, няма разлика ...ако скоро стане, постоянно пингвам, ще постна същия изход от командите, когато я дава грешката, за съжаление нямам идея как да я предизвикам
