Hi @Jagadesh,
Thanks for contacting Microsoft Q&A platform.
sorry to hear that the containers restarted and it's still in a waiting state.
could you please Retrieve container logs and events, follow the steps from this link: https://learn.microsoft.com/en-us/azure/container-instances/container-instances-get-logs
in the meantime, to help resolve this issue, your container instances are stuck in the "waiting state" to stop those containers and then start the containers again and check if the issue resolved.
check this link to stop and start containers or use the azure portal.
Hope this help you.
