Summary : Userspace Out-Of-Memory (OOM) killer
URL : https://github.com/facebookincubator/oomd/
License : GPLv2
Description : Out of memory killing has historically happened inside kernel space. On a
: memory overcommitted linux system, malloc(2) and friends usually never fail.
: However, if an application dereferences the returned pointer and the system has
: run out of physical memory, the linux kernel is forced take extreme measures,
: up to and including killing processes. This is sometimes a slow and painful
: process because the kernel can spend an unbounded amount of time swapping in
: and out pages and evicting the page cache. Furthermore, configuring policy is
: not very flexible while being somewhat complicated.
:
: oomd aims to solve this problem in userspace. oomd leverages PSI and cgroupv2
: to monitor a system holistically. oomd then takes corrective action in
: userspace before an OOM occurs in kernel space. Corrective action is configured
: via a flexible plugin system, in which custom code can be written. By default,
: this involves killing offending processes. This enables an unparalleled level
: of flexibility where each workload can have custom protection rules.
: Furthermore, time spent livedlocked in kernelspace is minimized.
