oomd - Man Page

Userspace Out-Of-Memory (OOM) killer for Linux systems


oomd [OPTION] ...


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.
