Blacksmith not running: mmap: Cannot allocate memory about blacksmith HOT 5 CLOSED

Similar issue here.

Update: on my Ubuntu 18 system the default hugepage directory was /dev/hugepages. (mount |grep huge). I edited the hard coded directory in code to point here. Also configured the system with 1000 huge pages. This seemed to get me past the this mmap error.

I did notice that the mmap command is specifying 1gb huge page size, while it was set to 2mb on my machine. I am going to assume 1gb huge page size is required but would appreciate guidance.

Update 2:
Set huge page size to 1gb by editing etc/default/grub and reboot. Now hammering with no errors 🔨🚀

The huge page size adjustment works for me. Thanks @joe-desimone . Btw, do you meet the illegal instruction issue after solving this problem?

anyone has the same issue

I confirm that the page size adjustment worked for me aswell.

Add GRUB_CMDLINE_LINUX="hugepagesz=1G hugepages=1 default_hugepagesz=1G" in /etc/default/grub
Then you can run update-grub and reboot.

@AnaMazda Please open a new issue for the mmap problem. Also state details about your system (for example, you will encounter your described issue on macOS).
