The problem started a= few updates ago, sometime around 11.2-U6. I have been using the same system sin= ce FreeNAS 9.10 and it did not have this problem back then. The motherboard is= a Supermicro X8SIA which has dual onboard Intel 82574L Gigabit Ethernet Controllers. I noticed from my Zabbix logs this issue mostly seems to happen during or a= fter my backups run to the system, which occur over NFS. This is a lot of sustai= ned traffic from two hypervisors backing up all guest hosts. In the logs I get the same sort of error others shared: Apr 18 19:18:42 freenas em0: Watchdog timeout Queue[0]-- resetting Apr 18 19:18:42 freenas Interface is RUNNING and ACTIVE Apr 18 19:18:42 freenas em0: TX Queue 0 ------ Apr 18 19:18:42 freenas em0: hw tdh =3D 0, hw tdt =3D 905 Apr 18 19:18:42 freenas em0: Tx Queue Status =3D -2147483648 Apr 18 19:18:42 freenas em0: TX descriptors avail =3D 119 Apr 18 19:18:42 freenas em0: Tx Descriptors avail failure =3D 0 Apr 18 19:18:42 freenas em0: RX Queue 0 ------ Apr 18 19:18:42 freenas em0: hw rdh =3D 0, hw rdt =3D 1023 Apr 18 19:18:42 freenas em0: RX discarded packets =3D 0 Apr 18 19:18:42 freenas em0: RX Next to Check =3D 0 Apr 18 19:18:42 freenas em0: RX Next to Refresh =3D 0 --=20 You are receiving this mail because: You are the assignee for the bug.=
