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.
