It is good to automatically reboot your server when it runs out of memory. This will cause a minute or two of downtime, but it’s better than languishing in the swapping state for potentially hours or days.
You can leverage a couple kernel settings and Lassie to make this happen on Linode.
Adding the following two lines to your /etc/sysctl.conf will cause it to reboot after running out of memory:
vm.panic_on_oom=1
kernel.panic=10
The vm.panic_on_oom=1 line enables panic on OOM; the kernel.panic=10 line tells the kernel to reboot ten seconds after panicking.
