Hello,

Have you tried to increase vm.min_free_kbytes to something higher, that is
>=30000?

I think I have hit something similar on a box running nbd-server to export a
3 SATA disk raid0 block device over Gigabit Ethernet.
Increasing min_free_kbytes got rid of the messages for me... Though the load
on your system is much higher than on mine.

Regards

Cláudio
