Sounds like I was wrong about Hadoop. So to be clear, were you able to reproduce the issue with just the netcat? Can you send us the full dmesg and /var/log/messages? Also stats from ethtool -S and the full lspci -vvv? It might be easier to open a bug and attach the files there. Thanks.

Subject: RE: igb Detected Tx Unit Hang during network load Looking back at my logs, most of the Hangs occurred during the fetch phase of Nutch jobs (relatively easy on the processor, mostly just fetching web pages) with cpu usage hovering around ~30%~50%. That being said, it does spike pretty high occasionally. I also tested this this morning using netcat to send a 20 GB file full of random data to and from one of the nodes. The other machine in being used as the recipient and sender respectively was another node machine that has not been having network issues (and has different hardware completely). The results from this suggest that CPU utilisation is not the issue. The tests were run while Hadoop was down, and the machine was restarted after each test. When using the problem machine to transmit/send the 20 GB file, a Hang occurred within seconds (1~10 seconds) every time (6 times in 6 tests). While the network was up, CPU utilisation was between 10% and 15% with idle being reported as between 80% to 85%. The MSI-X interrupt queues were seeing between 1000 and 9000 interrupts per second while data was being transmitted, and data transmission down the wire was around 50 MB/s Rx and 90 MB/s Tx. When using the problem machine to recive the 20 GB file, a Hang only occurred twice during 6 tests. When there was a Hang, CPU utilisation was between 3% and 5%, with idle being around 90%. The MSI-X interrupt queues were seeing between 1000 interrupts and 4000 or 16000 interrupts depending on the queue. The data sent down the wire while it was working was around 100-110 MB/s Rx and around 2 MB/s Tx. When there was not a Hang, the network still became unresponsive in each of the 4 remaining test, although no error was reported or displayed in the logs or on screen. During these tests, it took anywhere from 10 seconds to 2 minutes for the network to become unresponsive. Processor utilisation looked similar, with around 4/5% being used, and around 90% reported idle. Interrupts were again between 1000 and 4000/16000 as above. Rx and Tx was also as above Setting InterruptThrottleRate to 8000 did not help. If you think it would be helpful, I can post and link the stats I've collected. I think I will still see if I can test Hadoop while somehow limiting it's CPU utilisation just to check. I also think I'll try sending data at increasing speeds to see at what point this becomes a problem.

Check your CPU utilization. My guess is that it's bogged down and is unable to handle all the network traffic. I'll keep asking around here to see if they have any suggestions.

I have two ASRock C2750D4I (Avoton C2750, 16GB ECC Memory, 2x Intel i210 Gigabit NIC, Link: http://www.asrockrack.com/general/productdetail.asp?Model=C2750D4I) boards that I've been trying to use as part of a couple of Hadoop nodes. My problem arises when I try an run a job on Hadoop. Everything will work fine, but then after a while I loose the network connection the the node with igb ... Detected Tx Unit Hang printed to the attached screen and kern.log (as well as syslog) (full output below). The systems (which are identical): ASRock C2750D4I Mother Board 2x8 GB Kingston ECC Memory 2x Intel i210 Gigabit NICs (part of the Mother Boards) 4x1 TB WD Red HDDs I am currently using the 5.1.2 igb module as the 5.2.5 version will not build on my system (see http://sourceforge.net/p/e1000/mailman/message/32526226/) This problem also occours when using the 5.0.5-k version that ships with Ubuntu 14.04. Solutions I have tried: Disabling MSI(-X): Unsuccessful -- I tried using the IntMode module parameter set to 0 (i.e. Legacy Mode). No noticeable effect. Setting InterruptThrottleRate to 5000: Unsuccessful -- No noticeable effect. Disabling EEE (Energy Efficient Ethernet): Unsuccessful -- No noticeable effect. Setting RSS to 1 (only using 1 interrupt vector): Counterproductive -- Caused Tx Unit Hangs to occour more frequently. (I currently have this set to 4, the max) Disabling TSO (TCP Segmentation Offload): Improvement -- Disabled using ethtool. Tx Unit Hangs still occour, but the network is up and doing work for longer before this happens. Bonding both Ethernet ports using ifenslave-2.6: Improvment -- Tx Unit Hangs still occour, but the network is up and doing work for longer before this happens. Once a Tx Unit Hang occours, the only way that I have been able to get the node back on the network is by rebooting. I have tried ifdown and ifup with no effect. I've taken to running dstat on these two nodes to try and see what might be happening when they go down. Usually (but not always) there is a (large) spike in sent data just before the Tx Unit Hang. This is usually (but not always accompanied by a high number of interrupts on the MSI vectors. If you would like to see these I can pastebin them. I know there are a few pages and threads about this topic (and a mention in the README); however the majority of cases where this issue is raised don't seem to have been solved (the original poster usually just bought new NICs) or the proposed solution has not worked for me. Unfortunatly I can't just get new NICs, so I'm left trying to fix this problem.
