Hi, I’m just trying to get grin-miner working; I’m not trying to beat any records. I have a vanilla build with a vanilla toml configuration file. When I run grin-miner, it gets SIGKILL’d pretty much immediately after connecting to my grin server. “dmesg” reports:

[4767.004953] Out of memory: Kill process 4024 (grin-miner) score 738 or sacrifice child  
[4767.004964] Killed process 4024 (grin-miner) total-vm:4268340kB, anon-rss:3332204kB, file-rss:0kB, shmem-rss:0kB  
[4767.093858] oom\_reaper: reaped process 4024 (grin-miner), now anon-rss:0kB, file-rss:0kB, shmem-rss:0kB

I had thought 2.5GB to 4GB would be the minimum, but I get the above on a VirtualBox machine of 4GB. Is the official minimum documented? Sorry if I’ve missed it.

Thanks,  
David

FWIW, up’ing my VM to 5GB solved the problem. Perhaps memory requirements should be documented (apologies again if I missed it). David
