Hello,

 

I am trying to run urbit on my CuBox-i 4×4 and it looks like ARMBIAN 5.25 stable has some kind of kernel config that limiting the memory usage:

./urbit -c mytestcomet 
~
urbit 0.4.4
urbit: home is mytestcomet
boot: mapping 2048MB failed
see urbit.org/docs/using/install for adding swap space

I have added a 4GB swapfile but it seems it's not addressable by the urbit process, I also tuned the setting vm.swappiness without any success.

 

Could this be related to the kernel config CONFIG_VMSPLIT_2G? 

 

 

Details:

Kernel setting

cat /proc/config.gz |zcat |grep -v "^#" |grep VMSPLIT  
CONFIG_VMSPLIT_2G=y
