Network Card Lose Connectivity After A Few Days

[Kurtis Pullin]

Hi, I have Proxmox setup as a home server and lab with about 2 or 3 machines installed on it. Every few days my server will lose network connectivity on my 4 port network card (but the onboard card still continues to work).

When looking on the syslog it is displaying:
igb 0000:03:00.0 Detected Tx Unit Hang
Tx Queue <0>
TDH <0>
TDT <1>
next_to_use <1>
next_to_clean <0>
buffer_info[next_to_clean]
time_stamp <106478146>
next_to_watch <00000000205ede0d>
jiffies <106478438>
desc.status <a8000>

Specs:
CPU: Xeon E3-1200

Network Card: 03:00.0 Ethernet Controller: Intel Corporation 8257GB Gigabit Network Connection (rev 02) ** Connected to my lan **
03:00.1 Ethernet Controller: Intel Corporation 8257GB Gigabit Network Connection (rev 02) ** unused **

04:00.0 Ethernet Controller: Intel Corporation 8257GB Gigabit Network Connection (rev 02) ** unused **
04:00.1 Ethernet Controller: Intel Corporation 8257GB Gigabit Network Connection (rev 02) ** unused **

00:19.0 Ethernet Controller: Intel Corporation 82579LM Gigabit Network Connection (rev 04) ** On Board **

Fibre Channel Card: 07:00.0 Fibre Channel: QLogic Corp. ISP2432-based 4Gb Fibre Channel to PCI Express HBA (rev 03)

Any ideas or suggestions will be greatly appreaciated. I have tried a complete reinstall of the server but am still having the same problem. Thank you

Hi,

please update to the current kernel if you are not on 4.15.18-11-pve and check if the problem still exists.
