📰 Dev.to · Lyra
Learn to prevent Linux memory death spirals using systemd-oomd and PSI pressure signals
Action Steps
- Install and enable systemd-oomd on your Linux system using the command 'sudo systemctl enable systemd-oomd --now'
- Configure cgroup policies to target specific services and prevent memory overallocation
- Monitor PSI pressure signals using tools like 'ps -o pid,cmd,%mem --sort=-%mem' to identify memory-intensive processes
- Adjust systemd-oomd settings to optimize memory management and prevent the OOM killer from kicking in
- Test and validate your configuration using stress testing tools like 'stress-ng' to simulate high memory load scenarios
