_This question originally came up in our Slack community and the thread has been consolidated here for long-term reference._

I’m self-hosting LiveKit agents on AWS ECS Fargate. Everything works except that when tasks are downscaling, some active sessions get disrupted.

What’s the recommended workaround for this? Should I switch to ECS with EC2 launch type?

**Fargate is not recommended** for LiveKit agents because ECS Fargate has a hard shutdown limit of 120 seconds. Sessions longer than 2 minutes can be terminated abruptly.

**Solution:** Use ECS with EC2 launch type instead.

For EC2 launch type, configure the drain timeout:

1. Set `drain_timeout` in your worker configuration: [Server options | LiveKit Documentation](https://docs.livekit.io/agents/server/options/#drain-timeout)
2. Set `stopTimeout` in your ECS task definition to be larger than the drain\_timeout

This allows active sessions to complete before the instance terminates.
