Amazon Linux EC2 Troubleshooting -- 2

My Amazon Linux EC2 instance is showing signs of stress—occasional service crashes and noticeable load spikes. The stack is Nginx in front of PHP-FPM, and everything sits on a vanilla AWS setup with the usual security groups and EBS volumes. I need a fresh set of eyes to jump in over SSH, review the configuration, and stabilise the box. Scope of work • Pinpoint the root cause of the crashes and high-load episodes, using CloudWatch metrics, log files, and any profiling tools you prefer. • Audit Nginx, PHP-FPM, and systemd settings, making sensible tweaks to worker limits, memory, and time-outs. • Check kernel limits, swap usage, and basic Amazon Linux optimisations to be sure nothing obvious is throttling performance. • Verify that core AWS items—security groups, IAM roles, EBS throughput, and instance type—are aligned with best practice. • Leave me with clear notes on what you changed (or didn’t), so the next deployment is painless. Acceptance criteria 1. Nginx and related services run for 24 h without an unexpected restart. 2. Average CPU and memory stay within a normal operating window (we can define this on kick-off). 3. I receive a concise change log and any tuned config files. If you are comfortable in AWS CLI, CloudWatch, and basic DevOps housekeeping, this should be a quick win. SSH access and CloudWatch dashboards will be provided as soon as we agree to proceed.
