I have the following set in /etc/sysctl.conf on a stable/13 workstation.=20 Am using zfs with 32GB RAM. vm.pageout_oom_seq=3D120 vm.pfault_oom_attempts=3D-1 vm.pageout_update_period=3D0 Since setting these here, OOM is a rarity. I don't profess to exactly know what they do in detail though. But my experience since these were set is hardly any OOM and big users of memory like firefox don't crash. --=20 J. --LPEGaSQsH9s0WkY8 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE8n3tWhxW11Ccvv9/s8o7QhFzNAUFAmJjEmkACgkQs8o7QhFz NAWfsQ/9FRdkcoQfbT1NK3Fg4dphc7J4+6Sfv9bvQ0NYM3cfjQ2u/Y96Jm0CF0zN DZq+TNM2QDk1P+oOUgqc8BrOebaAbVraQYKeB8kSjdk99OMYGgqLeJsrkpM5uE4f OsvTEBCV/sWJx69GUAeXLLugMgB4J62bC6GMYehMBtAd+XTXtmTfoHXdZpRWIxDU 85dR2gnwS+YTLWpxDhTls8O26aWwi4lkOSnQ8H0CqPwOBMgRDmaGQVaze45wam3h Xgywca4g7ROVjBJymuZ9XoON+qyOy468UVu8Hqu5HbsCg+LSMP4dE4z7Ew7ul//1 xe5AWBOaprHRuQrvTDIoITogDeV2P+ViFPbZsjXgLglHeTGsI0rGPXj3M3MJuor9 BrOUg2TFjieNdUXdYMYrwp8NsZMwOOQKbTxKxEkvr/na5UxIK/YS1vaCLmfIUbbR LdXeub0xtkc3B3OPeaNmI2VROGtXw6Dy7Y8g1j639P0NU/4/tl9yuC61iT4qctAk FzcmXjSA5EgrMtRcv0wIHVex5yNsgS36v3ftFNzKBiUo50/O+sVg/C7HZlPTdKGF FN/UJxF4t94wuI/F1o89++tyi7DIfJWWRQv8dHoja4RtkHo5xYsdVetBLDIRaljn uArYzJKvomBF+vurdRxjIrVV/7CfCZkUXQLIbDaIpwqHEKFlToE= =FQCd -----END PGP SIGNATURE----- --LPEGaSQsH9s0WkY8--
