AWS Ec2 Status Check Fail Reason

Question

Hello Everyone,
                          I have a t2.xlarge Ec2 instance where i am running my algorithm docker containers. This is spot instance. But sometimes the ec2 instance 2/2 status checks is getting failed and my resources is getting stopped. Previously it used to happen very rarely but recently it started happening regularly. Is there any configuration error i am doing and can you guys help me how to mitigate this error??

Hello,

Increasingly frequent status check failures on your t2.xlarge spot instance could be due to **hardware issues or your instance configuration** . Here's a quick approach:
* **Disk Space:** Monitor usage and configure docker to clean up old data to avoid filling the disk.
* **Resource Limits:** Ensure containers have enough CPU, memory to run smoothly.
* **Updates:** Keep OS and software up-to-date with security patches.

Check CloudWatch Logs: Look for errors during boot or instance health messages https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/CWL_GettingStarted.html.

**Restart the Instance:** A simple restart can resolve temporary glitches
