I'm not an expert but I'm unimpressed with the way FreeBSD handles an OOM situation on a desktop. I have a FreeBSD desktop PC at home which is always under memory pressure: Xfce, my Firefox, my wife's Firefox with lots of tabs, several bhyve guests, a SMB server and other stuff. So the "swap_pager_getswapspace(11): failed" situation is rather frequent.=20 FreeBSD freezes, then kills some innocent random processes like local_unbound, then it may slowly recover. Sometimes it guesses correctly and kills the offender (firefox most often). --=20 Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/ --Nq2Wo0NMKNjxTN9z Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJfHSOYAAoJEA2k8lmbXsY0jB4H/2iYypfJ+zx9hDAaXRnbx0zy LMmnVVjP74EREm5gK2TZ6j8f6oGl1c/8I53okFteZ9n5aZn16jbT4+DqgO2M3U6l ytyZsM1JW5CVAcDgQPXLBz0BG7kjy4dgOiNZx3LvML0YUC1cKr50j5CapGGr4Ick NZRCcZlvOPMIWYw0N0ltqzmXuW46OWvgu6qXe2wHU1g5RJJkVdkEaUaWYJlTqbmo HdbrD8vnVfnBD7lVAALXEqRDrjggvw544We6LQblbAHCJNbgrPp6/C+cFvjabh+H a+CWohmIzvVmL9bMr1k+xTNw7eSDWLH/4rg+AmxVf1rOHjVXgJUna8PRPs0s8bY= =WX1q -----END PGP SIGNATURE----- --Nq2Wo0NMKNjxTN9z--
