Instance stoped working

Hi,

From the screenshot, I was able to check your instance ID and using our internal tools I noted the following error in console logs

 [   11.367264] cloud-init[603]: OSError: [Errno 28] No space left on device
 [   11.371686] cloud-init[603]: During handling of the above exception, another exception occurred:

Therefore it appears the reason for your issue is that your filesystem has reached capacity and you will need to increase volume size and extend filesystem.

To get console output

1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/
2. In the left navigation pane, choose Instances, and select the instance.
3. Choose Actions, Monitor and troubleshoot, Get system log.

To resolve this issue you will need to take the following actions,

1. Increase volume size: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/requesting-ebs-volume-modifications.html
2. Expand File system: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/recognize-expanded-volume-linux.html
