Description

bustd - Lightweight OOM Killer Daemon

bustd is a lightweight process killer daemon for out-of-memory scenarios for Linux. It's designed to be more efficient and responsive than traditional OOM killers, with extremely low memory and CPU footprint.

Key Features

• Extremely Low Memory Usage: Uses significantly less memory than other OOM killers
• Efficient CPU Usage: Uses adaptive sleep times and the fast sysinfo syscall
• Smart Memory Pressure Detection: Uses Linux Pressure Stall Information (PSI) for accurate memory pressure detection
• Memory Lock: Uses mlockall to ensure the daemon stays responsive even under heavy memory pressure
• Systemd Integration: Runs as a systemd service for reliable operation

Installation Instructions

1. Enable the COPR repository:

sudo dnf copr enable boobaa/bustd

2. Install bustd:

sudo dnf install bustd

3. Enable and start the service:

# Enable the service to start on boot
sudo systemctl enable bustd

# Start the service immediately
sudo systemctl start bustd

4. Verify the service is running:

sudo systemctl status bustd

Configuration

By default, bustd will:

• Kill processes when memory pressure causes 25 microseconds of stall time in the last 10 seconds
• Run as a systemd service with automatic restart
• Lock itself in memory to prevent being swapped out

Troubleshooting

1. Check if the service is running:

sudo systemctl status bustd

2. View logs:

journalctl -u bustd

3. If you need to stop the service:

sudo systemctl stop bustd

Uninstallation

1. Stop and disable the service:

sudo systemctl stop bustd
sudo systemctl disable bustd

2. Remove the package:

sudo dnf remove bustd
