EC2 Amazon Linux Instance becomes unresponsive when I run my server on it.

Question

Hi

I recently created a new EC2 Linux t2.micro instance and have downloaded the necessary resources to run a Minecraft server on it. However, while running the server, it starts loading, and within a minute the instance becomes unresponsive. I am then unable to perform any commands or SSH into it until I restart it.

Does anyone have an idea as to what might be going on? Is it that the server doesn't have enough resources to run the server? I have run a Minecraft server on a t2.micro Windows instance before, and that worked fine, so I assumed Linux would be okay too.

Any help would be much appreciated.

Answer

An EC2 instance that launches successfully before running a Minecraft Server (MS) may indicate MS is maxing out resources, which causes the instance to become unresponsive. Consider enabling CloudWatch monitoring to observe CPU, memory and other metrics before and after launching MS to isolate the root cause. It is also possible that a more robust instance type than t2.micro is required. Lastly, consult MS documentation to help optimize how the server runs on the instance.
