+**Note:**
+If there is no real memory available, the system might become unresponsive. To help mitigate this, consider raising the value of vm.v_free_severe (as well as vm.v_free_min and vm.v_free_target such that v_free_severe < v_free_min < v_free_target). For instance, on a system with 3GB of RAM, JohnNielsen was able to prevent a reproducible out-of-memory hang by setting vm.v_free_severe=7168.
