Summary0015195: ixgbe driver 5.1.0-k-rh7.5 generates network instabilities and the machine finally losses connectivity
DescriptionSeveral servers with network card Intel(R) 82599 10 Gigabit Dual Port experience network instabilities that cause them to finally loss connectivity. The machines are using the driver ixgbe version 5.1.0-k-rh7.5 provided by the CentOs7 kernel 3.10.0-862. The OS does not report any special error in messages.

Updating the driver to version 5.3.7, the issue seems to be solved. It is required to recompile the driver for each new kernel version.

Is it possible to provide the upcoming kernel releases with ixgbe driver version 5.3.7?
Steps To Reproduce* Install a machine with network card Intel(R) 82599 10 Gigabit Dual Port with CentOs7 and kernel family 3.10.0-862
* Let the machine works normally doing transfers through the network
* The machine finally losses connectivity after a few hours

CentOS only rebuilds the kernel SRPM provided by Redhat for RHEL. You would need to get RH to update it in the RHEL SRPM by reporting it on

I'd also say this is not a universal problem. I have Intel x710 cards in use 24 hours a day and haven't seen any problems. Are you using the latest firmware for your cards? Current kernel version is 3.10.0-862.11.6.el7

Thank you very much.

We are using the last kernel version 3.10.0-862.11.6.el7.x86_64 and we try to keep updated the firmware.

We will proceed to report the issue to
