Excuse me the AWS ec2 suddenly hang up automatically restart again, is what problem, please give advice or comments

CodePudding user response:

There are two possible ways
1. AWS problem, what the underlying physical machine has a problem
2. The system itself is unusual, by observing the performance curve, such as CPU mem to observe

In addition, after the restart, may have a look/var/log/message screen, see if there are any suspicious of log,
