Memory leaks are the silent killer of long-running Linux servers, often causing gradual performance degradation until a reboot is forced. In this episode, we explore how modern Linux administrators diagnose and mitigate memory pressure using tools like Valgrind, Valkey, and cgroups to isolate runaway processes without disrupting live services. We look at a specific case study where a custom Python application caused subtle heap fragmentation, leading to OOM kills during peak traffic hours. Lucas and Luna break down the difference between virtual memory leaks and physical page cache exhaustion, offering concrete strategies for setting up automated alerts based on RSS versus VSS metrics. You will learn how to configure systemd resource controls to limit individual service memory usage, preventing one buggy microservice from bringing down the entire host. This episode provides actionable steps for sysadmins managing high-availability infrastructure in September 2026, focusing on stability over brute-force restarts. #FexingoBusiness #BusinessPodcast #LinuxServerAdmin #SysadminLife #SystemEngineering #MemoryManagement #LinuxAdministration #DevOpsTools #PerformanceTuning #ServerStability #OOMKills #Cgroups #Valgrind #PythonOptimization #InfrastructureOps #TechCareers #SoftwareEngineering #CloudComputing Keep every episode free: buymeacoffee.com/fexingo
