Out-of-memory kills are reported
When Linux ends a program because its sandbox ran out of memory, the command's result, its process and the stream's exit event carry outOfMemory: the code out_of_memory, how many processes were ended, the sandbox's memoryMiB and a hint (1,024 MiB or more, or a resize while paused). Each such command also sends the event sandbox.out_of_memory to your webhooks. See when a program runs out of memory.
