The solution I came to is very simple. Currently I only need one of em (dual card), so I disabled the second one. When I boot the router, my network usage rises up to 96%. I simlpy mark that unusable interface (em1) as up and few seconds later I mark the same interface down. My network usage drops significantly, currently I am looking it shows 75%. The router is running without locking for 25 hours now. I am also planning an upgrade to 4.1 if there are changes to em driver. Best regards, Mitja
