Less Available RAM after upgrading to Amazon Linux AMI 2.0.20251209 x86_64 ECS HVM GP2

[FinnIckler]

We have this terraform code that automatically chooses the newest version of the amazon linux 2 ecs ami

data "aws_ami" "ecs" {
  most_recent = true

  owners = ["amazon"]

  filter {
    name   = "owner-alias"
    values = ["amazon"]
  }

  filter {
    name   = "name"
    values = ["amzn2-ami-ecs-hvm-*-x86_64-*"]
  }
}

After upgrading to Amazon Linux AMI 2.0.20251209 x86_64 ECS HVM GP2 yesterday, we noticed today that the available memory went from 7821MiB to 7817MiB on a m6i.large which caused us to not fit two containers on one instance.

Was this an intended change? Is there a way to avoid this happening in the future?
