The lowmemorykiller driver lets user-space specify a set of memory thresholds
|
|
where processes with a range of oom_adj values will get killed. 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.
