Based on my calculations, that maxswzone is good for just under 1GB swap. What do you see have for vm.swap_maxpages and vm.swzone? >> Synth is still crashing hard, same issue. >An update. Synth still crashed with one swap zone of 16GB. What do you mean by "swap zone"? Do you mean you have one 16GB swap device? >stack overflow. As I say, there was no warning. Everything was fine, >then memory usage went through the roof! I've just tried building llvm80 via ports on my laptop, using the same options as you. I have 4GB RAM and 4GB swap with system defaults and had no problems with an 8-way build. The highest swap usage I noticed was <500MB. I suspect your problems are related to either ccache or synth. >The second one, hopefully, contains every log up to the one that >crashed and hopefully also the beginning of that task.

You should be able to do a single-theaded build of llvm80 in 4GB RAM without problems. That said, I notice that the first log file suggests you were building 3 ports in parallel, and each port build was running 3 jobs - that's 9 jobs in parallel on a low-spec CPU with 4 threads. You should limit the number of CPU-bound processes to the number of CPU threads you have.  cd /usr/ports/devel/llvm80 && make -- Peter Jeremy
