OOM

Out of Memory — what happens when a process exceeds its allocated RAM and the OS kills it.

Definition

An Out-Of-Memory event occurs when a process requests memory the system cannot satisfy. On Linux the OOM killer terminates the worst offender to free RAM. Common triggers in automation: an n8n workflow loading a huge dataset into memory, a Node process leaking, a container hitting its cgroup limit. Mitigations: stream data, raise limits, paginate.
