 ## Overriding the machine when triggering
 
 You can also override the task machine when you [trigger](/triggering) it:

 This is useful when you know that a certain payload will require more memory than the default machine. For example, you know it's a larger file or a customer that has a lot of data.

+## Out Of Memory (OOM) errors
 
 Sometimes you might see one of your runs fail with an "Out Of Memory" error.
 
 > TASK_PROCESS_OOM_KILLED. Your task ran out of memory. Try increasing the machine specs. If this doesn't fix it there might be a memory leak.
 
-If this happens regularly you need to either optimize the memory-efficiency of your code, or increase the machine.
+We automatically detect common Out Of Memory errors, including when ffmpeg throws an error because it ran out of memory.
+
+You can explicitly throw an Out Of Memory error in your task. This can be useful if you use a native package that detects it's going to run out of memory and then stops before it runs out. If you can detect this, you can then throw this error.

+```ts /trigger/heavy-task.ts
+import {  task } from "@trigger.dev/sdk/v3";
+import { OutOfMemoryError } from "@trigger.dev/sdk/v3";
+
+export const yourTask = task({
+  id: "your-task",
+  machine: "medium-1x",
+  run: async (payload: any, { ctx }) => {

+    throw new OutOfMemoryError();

+});

+If OOM errors happen regularly you need to either optimize the memory-efficiency of your code, or increase the machine.

   This will only retry the task if you get an OOM error. It won't permanently change the machine that a new run starts on, so if you consistently see OOM errors you should change the machine in the `machine` property.
