Hello,

I have a server with 8 VFs over Intel 82599 10Gb adapter
A test iterates DPDK process over each VF in turn for 10 sec:

while [ 1 ]; do
	for vf in $VFS; do run_dpdk $vf; done
done

After several minutes server crashes.
The crash does not trigger kdump or leaves traces on console
The server power cycles

The crash reproduced on several different servers

Does anybody familiar with this fault ?
It there a way to stop it ?

Setup:
CentOS 6.8 x86_64
ixgbe-4.3.15
DPDK-16.11

Regards,
Gregory
