Could you please share some details about your configuration?
(amount of memory, arch, ...)

On my platform the test works, except if I use a very low amount
of memory (few MBs).

Thanks,
Olivier

The QA reported this issue on an octeontx2 machine.
But when I tested on an x86 server it was reproducible(That above log
was with x86 server, 56 cores + 2 NUMA). So I thought
it is a generic issue(I did not spend any time debugging this). Now
debugged the failure on x86,
it was the case of low memory. I will debug more on the octeontx2 failure case.
