Hi folks,

Has anyone else seen dmesgs about page allocation failures? I see many of these in dmesg:

iperf3: page allocation failure. order:2, mode:0x20
Pid: 26768, comm: iperf3 Not tainted 2.6.32-642.4.2.el6.web100.x86_64 #1
Call Trace:

There's an old issue from rhel6.4 https://access.redhat.com/solutions/90883 but it's not clear if these is bad or just noisy.

Do these messages imply performance issues or even something amiss with the hardware (nic/ram)?

Thanks for any pointers,
