For the case of devel/llvm13 (Pi4, -current, make) defaults. Those seem to be: vm.pageout_oom_seq: 12 vm.pfault_oom_attempts: 3 vm.pfault_oom_wait: 10 With 8 GB RAM I didn't anticipate memory problems 8-( For the case of practical interest (Pi3, stable/13, buildworld): vm.pageout_oom_seq: 4096 vm.pfault_oom_attempts: 20 vm.pfault_oom_wait: 10 It appears I should increase the latter two for starters. Can the Fortran feature be turned off in buildworld? That's the troublemaker for me. Thanks for writing! bob prohaska
