Any limit on the number docker compose-based Greengrass components

Question

I have a Greengrass device with 5 components built with docker-compose, but I am having the following problem:
1. All 5 components are built with `docker-compose`: In this case, when I run all these components, only the containers of 4 components are running and showing in `docker ps`, but all the components are shown as `RUNNING` in Greengrass: `/greengrass/v2/bin/greeengrass-cli component list`
2. Use 4 docker compose-based component and 1 docker-based component (`docker run --name` in run lifecycle): In this case, all the components are shown as `RUNNING` in `/greengrass/v2/bin/greeengrass-cli component list` as well as with `docker ps`

My question is that is there any limit on the number of docker compose-based component or any configurations to fix the issue?

There is no strict limit on the number of Docker Compose-based components in AWS Greengrass.

1. System resources: The number of components that can run concurrently depends on the device's resources (CPU, memory, disk space, etc.).
2. Docker container limits: Docker has limits on the number of containers that can run simultaneously (typically around 100-200 containers per Docker daemon).
3. Greengrass component limits: Greengrass has a soft limit of around 20-30 components per deployment. Exceeding this may cause issues
