I ran a 'make build' Friday night on 4.0, along with 'stress --vm 1 --cpu 33' but it was still trying to configure apache after several hours, so I cancelled the stress, changed hw.setperf to 100 and let it grind away. The next morning I found the system frozen at the libc build stage (qsort.o). I'm not sure that any of this is really significant since under 4.0 this machine freezes up even when the system is completely idle for hours on end. Yesterday I reverted back to 3.9 and did another 'make build', with hw.setperf also at 100. It completed without any problems (no sig11, crash, freeze or anything out of the ordinary). If you think it's worthwhile to try that again with more load, what stress parameters do you suggest?
