EC2 instance fail every week

Question

Every week 1/2 status check fail in my Ec2 instance: "Instance reachability check failed". I get unable to connect it using SSH (Putty) and the only way to fix it is by rebooting the instance. So in the end I manually need to reboot my EC2 instance every week. Thats frustrating. Is it normal or do I have a technical issue in my instance?

Answer

Hello,
My recommendation is to search in the OS logs, maybe is an out-of-memory issue, or exausting of any other resource (open files, processes, etc), check the /var/log/messages file and any other files there. Normally when the Status Check that fails is the "Instance status check" the issue is in the app or OS and not on AWS side.

Also see if increasing the memory (by using a larger instance) makes the issue go away or if it takes longer to happen.

Hope this helps.
