As a matter of curiosity, have you been able to run a -j4 buildworld to completion on your RPI3? If so, please post your setup. For several months now all my attempts at j4 buildworld have failed with "killed, out of swap" even though top seems to report minimal swap usage. It even happens with no -j value set at all, but usually restarting with -DNO_CLEAN allowed progress to pick up where it left off. Alas, as I write this, the kernel just reported Jun 1 08:34:34 www kernel: pid 19399 (c++), uid 0, was killed: out of swap space top is showing Swap: 4096M Total, 17M Used, 4079M Free but since top is alive the value is stale. Nonetheless, I have seen top killed while still showing minimal swap usage. It seems as if the "out of swap" kills are being issued in error.. Thanks for reading, bob prohaska
