One may have to sit in front of an unresponsive system, +listening to the grinding disk for minutes, and press the reset +button to quickly get back to what one was doing after running out of +patience. + +earlyoom is a userspace daemon that can be triggered earlier than the +kernel's OOM-killer. It checks the amount of available memory and free +swap up to 10 times a second (less often if there is a lot of free +memory). By default if both are below 10%, it will kill the largest +process (highest oom_score). The percentage value is configurable via +command line arguments. + +To enable it, put this line in your rc.local after running chmod +x on +/etc/rc.d/rc.earlyoom: + +if [ -x /etc/rc.d/rc.earlyoom ]; then + /etc/rc.d/rc.earlyoom start +fi + +...and to have it exit at shutdown, put this in your rc.local_shutdown: + +if [ -x /etc/rc.d/rc.earlyoom ]; then + /etc/rc.d/rc.earlyoom stop +fi + +A log file for it is kept at /var/log/earlyoom.log, and earlyoom can +be configured by modifying /etc/default/earlyoom. |
