Hi, I configured an EC2 instance with following settings :
- AMI : ami-082af980f9f5514f8
- Platform : Linux/UNIX
- Instance type : t3.micro (CPU credits : unlimited)
- Storage : 50 Go EBS
- Associated with an Elastic IP address
- Associated to Security Group to restrict SSH access.
Configuration is pretty basic, no snapshot is scheduled.
But I noticed random crashes not related to apps deployed on the instance.
About once a day, I'm seeing a peak in CPU usage of almost 100%, which seems to be linked to an incoming network of the order of a few hundred kB. Then the instance status checks fail and can't be access anymore even with SSH... I created an alarm on status checks to automatically restart EC2 instance on failure, but sometimes it's not enough and I have to manually stop and start the instance.
I have to find a better solution and fix this issue in order to use my EC2 instance.
Do you have any idea of the source of the problem please?
