You have enough free memory so it's not swapping.

From my system just now:
105M Act, 8072K wired, 15M Exec, 68M File, 2844M Free
Swap: 1372M Total, 1372M Free

Last week I had too many sysbuild jobs which had my system
almost unusable before sysbuild crashed. I've now split
sysbuild jobs into four sets to run without swapping on
different days.
