I just got another lockup.
It looks like in the time of lockup the number of Ierrs is increasing:
Name Mtu Network Address Ipkts Ierrs Idrop Opkts Oerrs
Coll
em2 1500 <Link#3> 00:14:4f:XX:XX:XX 13060395 18438 0 6579984 1
0
After "ifconfig em2 down;ifconfig em2 up" Ierrs stays at 0 rate for long time.
Without DEVICE_POLLING it was similar situation.
