Specify the +minimum oom_adj values in /sys/module/lowmemorykiller/parameters/adj and the +number of free pages in /sys/module/lowmemorykiller/parameters/minfree. Both +files take a comma separated list of numbers in ascending order. + +For example, write "0,8" to /sys/module/lowmemorykiller/parameters/adj and +"1024,4096" to /sys/module/lowmemorykiller/parameters/minfree to kill processes +with a oom_adj value of 8 or higher when the free memory drops below 4096 pages +and kill processes with a oom_adj value of 0 or higher when the free memory +drops below 1024 pages. + +The driver considers memory used for caches to be free, but if a large +percentage of the cached memory is locked this can be very inaccurate +and processes may not get killed until the normal oom killer is triggered. + |
