(In reply to Mark Millard from comment #3)

By the way, for reference:

# sysctl -d vm.pageout_oom_seq
vm.pageout_oom_seq: back-to-back calls to oom detector to start OOM

(As I remember teh default is 12 for the above.)

# sysctl -d vm.pfault_oom_attempts
vm.pfault_oom_attempts: Number of page allocation attempts in page fault
handler before it triggers OOM handling

(-1 for the above disables the pfault OOM handling.)

# sysctl -d vm.pfault_oom_wait
vm.pfault_oom_wait: Number of seconds to wait for free pages before retrying
the page fault handler


All 3 of those show up under both sysctl -T and sysctl -W .
