That is very important to know. It should be mentioned in the report. So I tried to reproduce it. To get even the mmap() in the test to succeed I needed to also pass default_hugepagesz=2MiB. Also 1GiB of memory was not enough. 30GiB was however. But then the tests succeeds fine for me. So I'll need reproduction steps. Thomas
