Neural Engine Root Cause Analysis
High CPU utilization detected — the server's processor is at or near capacity, causing degraded application performance, increased response times, and potential service unavailability. Common causes include runaway processes, sudden traffic spikes, inefficient code paths, or crypto-mining malware.
Remediation Plan
1. Identify the top CPU-consuming processes using 'top' or 'htop' on the affected server.
2. Check for runaway or zombie processes and terminate them if safe to do so.
3. Review application logs for tight loops, excessive logging, or unoptimized queries.
4. Scale horizontally or vertically if the load is legitimate.
5. Check for unauthorized processes (crypto miners) if CPU usage is unexplained.
Improvements Applied
- Pattern classified as HIGH_CPU (expected CONTAINER_EVENT)
