# Avoid dead loops

Sometimes you might see the message **MAX\_ACTIONS exceeded** in your AI workflow:

This error occurs when an infinite loop (without user interaction) is accidentally created between [Blocks](/ai-chatbots-and-automation/visual-builder-101/how-to-create-a-block.md):

The system limits the number of Actions that can run without user interaction. Each time the user interacts, the MAX\_ACTIONS counter is reset.

In some cases, a loop in the background is useful — for example, when polling a remote API until the required data is available. If you expect the loop to run many times, you can prevent the **MAX\_ACTIONS exceeded** error by adding a **Wait Action** with at least 1 second of delay inside the loop:

Keep in mind that any Flow without user interaction — including loops — can run for a maximum of 4 hours. After this time, the Flow will stop automatically at whatever step it has reached.
