-zone_reclaim_interval:
+panic_on_oom
-The time allowed for off node allocations after zone reclaim
-has failed to reclaim enough pages to allow a local allocation.
+This enables or disables panic on out-of-memory feature. If this is set to 1,
+the kernel panics when out-of-memory happens. If this is set to 0, the kernel
+will kill some rogue process, called oom_killer. Usually, oom_killer can kill
+rogue processes and system will survive. If you want to panic the system
+rather than killing rogue processes, set this to 1.
-Time is set in seconds and set by default to 30 seconds.
-
-Reduce the interval if undesired off node allocations occur. However, too
-frequent scans will have a negative impact onoff node allocation performance.
+The default value is 0.
