My 2 cents here. I would keep the default to use more CPUs, as nowadays I suspect that most devs have a way more than 8GB installed. The worse machine I use here to build Kernel is a Gen-3 i5 that has has 16GB (and it is a personal laptop I bought 5 years ago). Yet, I agree that doc build should be saner on low-cap machines. Ideally, the fix should be, IMHO, at sphinx-build: -jauto should detect OOM possible conditions and reduce the number of used CPUs it the max available memory is too low. As there's now a script at Kernel, maybe the script could be modified to detect if the max available memory is too low, passing -j1 if, let's say, the machine has less than (let's say) 16 GB RAM. > >> At least 2 times I also had system freezes where I had to power > >> cycle to reboot. That sounds weird. I can't imagine why you would experience system freeze with doc build.
