The swap layout was sub-optimal, with a 2 GB partition combined with a 4 GB partition. A little over 4GB total seems usable. A few days ago the same attempt stopped with a series of OOMA kills, but in each case simply restarting allowed the compile to pick up where it left off and continue, eventually finishing with a runnable version of chromium. In this case swap use peaked a little over 4 GB. Might this suggest the machine isn't freeing swap in a timely manner? Thanks for reading, bob prohaska
