Network interfaces crash for 2-6 second, when CPU utilization is 100%

[Lokin]

Goof afternoon.

I have 4 computers, each with 4 INTEL 82574l network cards, and when the processor load is 100%, the network traffic on all network cards disappears. Please tell me why this is happening and what may be the reason. Network only LAN(IP+mask, no gateway). Capture wireshark shows how the TCP flow interrupts.

 

 

 

 

 

Configuration:
CPU: Intel Core i7 6700 @ 3.40GHz
RAM: 16,0ГБ
MB: ASUS PRIME H270-PLUS (LGA1151)
HDD: Fake INTEL RAID-1 - WDC HDD 1TB
OS: Windows 10 Pro 64-bit 21H1
NIC: 4 x Intel 82574L

What have you tried:
Updated windows 1909 -> 21H1
bios updated 1205 ver (last stable)
Tried changing different settings on the network card

Hello Lokin,

Thank you for posting in Intel Ethernet Communities. 

For us to further check the issue, please provide the following details.

1. Are you using onboard/embedded 82574L?
2. Can you share the link of your latest driver?
3. Can you also tell us what is the application running that makes your CPU utilization run at 100%?
4. When did you start encountering this issue?

If you have questions, please let us know. In case we do not hear from you, we will make a follow up after 3 workings days. Thank you.

Best regards,

Hello, Michael.

1. Each computer has 4 x 82574l. Discrete network cards

2. This is the standard Windows 10 driver. e1i65x64.zip

3. This is a monitoring system, it processes signals from many devices. Or I can run the archiver (7zip/Winrar), it will load the processor up to 95-100% and the network may also disappear several times.

4. The problem has always been. 2 months

Hello Lokin,

Thank you for providing the details that we requesting. Upon checking the details that you provided, let me check. Have you tried contacting the manufacturer of the board since the network card is onboard. The problem with onboard components is they sharing resources with the rest of components. They may have some recommendations on this issue.

If you have questions, please let us know. In case we do not hear from you, we will make a follow up after 3 workings days. Thank you.

Hello Michael,

I'm sorry, I misunderstood the translation of the word onboard. I have discrete network cards in the PCI express port.

Hello Lokin,

Thank you so much for the clarification. So all of the 4 cards are giving the same problem on different system? Can you take a photo on both sides of the cards focusing on the markings and also if you still have the box for me to validate the card.

If you have questions, please let us know. In case we do not hear from you, we will make a follow up after 3 workings days. Thank you.

Hello Michael,

Yes, all 4 computers have the same components and have the same problems. I can’t take a picture. The servers are located remotely and the shutdown is not planned in the near future. Can I get information programmatically? There are no such network cards for you.

Hello Lokin,

Thank you for letting us know and we understand. Kindly help generated the SSU logs instead. We will try to check if the cards will be detected as PCIe cards. Please download the utility here:
