Identifying the Root Cause: Indexing Lock Conflicts and High CPU When performing bulk stock updates on AWS-hosted applications, particularly those relying on relational databases like MySQL or PostgreSQL, a common symptom is a dramatic spike in CPU utilization, often accompanied by slow response times or even application unresponsiveness. This behavior is frequently a direct consequence […]
Diagnosing OOM Killer Invocation on PHP-FPM Workers The Linux Out-Of-Memory (OOM) Killer is a critical system process designed to reclaim memory when the system is under severe pressure.

When integrating legacy SOAP services into modern C++ applications, developers often encounter XML parsers that are not configured with security best practices. This oversight can expose the application […]
Identifying the Culprit: Initial System-Wide Checks Before diving deep into specific daemon processes, a quick system-wide assessment is crucial. This helps establish a baseline and rule out broader infrastructure issues on your DigitalOcean droplet. Start by checking overall system resource utilization. High CPU or memory usage can often point to a runaway process, not necessarily […]
