Out of Memory (OOM) refers to a computing state where all available memory, including swap space, has been allocated.

Normally this will cause the system to panic and stop functioning as expected.
There is a switch that controls OOM behavior in /proc/sys/vm/panic_on_oom. 
When set to 1 the kernel will panic on OOM. 
A setting of 0 instructs the kernel to call a function named oom_killer on an OOM.
Usually, oom_killer can kill rogue processes and the system will survive. 
The easiest way to change this is to echo the new value to /proc/sys/vm/panic_on_oom.

# cat /proc/sys/vm/panic_on_oom 1
