[Ubuntu 20.04.1-latest] MEMORY ALLOC FAILED: mmap with HUGETLB failed, attempting without it (you should fix your kernel)

[yhilgjff]

Using Ubuntu 20.04.1 LTS fully patched while using xmr-stak-1.0.5-rx with the following system configs in place:

$ cat /proc/sys/vm/nr_hugepages 128 $ cat /etc/sysctl.conf | grep -i hugepages vm.nr_hugepages=128 $

But this worked fine using 19.10 and 18.04.

I have the same issue with 18.04. using xmr-stak-rx 1.0.5-rx af03d89

[Anarbb]

same problem here

[flipMWD]

I'm getting this running as sudo. As regular user it says MEMORY ALLOC FAILED: mlock failed

xmr-stak-rx-linux-1.0.5-cpu on Arch Linux, kernel 5.11.2.

[XumPZup]

same problem

[cuppajoeman]

I am also getting this issue on Kernel: 5.9.16-1-MANJARO

[KoNickss]

Also getting this on stock 5.11.4 linux kernel in archlinux but only when ran as sudo, running as user gives me MEMORY ALLOC FAILED: mlock failed. Mining still works but hashrates are insultingly low (1kH/h on a powerful PC)

Also getting this, even with large tlb on ubuntu 20.04

-- Seems broken in xmr-stak.

Available in case further info/testing is needed.

ah, I went in to config.txt and change to "no_mlck" instead of "warn" on ubuntu.

Works fine and it creates the pages it needs.

All good there.

this solved my issue

[yhilgjff]

Thanks to everybody's contribution.

As of 22.10 this problem still exists but can be fixed by replacing "warn" by "no_mlck" under the "use_slow_memory" option located in the config.txt of xmr-stak-rk.

Cheers!
