Estou usando um USB Thumb Stick de 16GB para uma unidade de troca, porque preciso fazer um processo que consuma muita memória. A unidade de troca diz que está listada e instalada, mas o ODROID está congelando por falta de memória quando atinge 2 GB. Aqui está a informação.

Mas quando o processo ativo é executado, o swap claramente não está funcionando.
Quando eu uso free -m você pode ver que eu estou completamente sem RAM e o swap ainda diz 0.
master@odroidxu4:~$ free -m

Atualmente, o ODROID está congelando e desligando devido à falta de memória.
Alguma ideia de como posso corrigir isso?

tentando o mkswap agora também ...
Na verdade, esse último mkswap transformou meu swapon -s em
