bustd
A lightweight Linux daemon that kills processes to prevent out-of-memory crashes using Pressure Stall Information.
What is bustd?
bustd is a lightweight Linux daemon that prevents out-of-memory system crashes by monitoring memory pressure and killing processes before the system becomes unresponsive. It uses Linux kernel Pressure Stall Information (PSI) to detect memory stalls and make intelligent decisions about which processes to terminate. The daemon is designed to be extremely resource-efficient, using minimal memory and CPU while remaining effective during memory thrashing.
Linux system administrators and users who run memory-constrained systems or servers and want to prevent out-of-memory crashes without significant overhead. It's particularly useful for embedded systems, low-resource servers, or any environment where memory reliability is critical.
Developers choose bustd for its minimal memory footprint compared to alternatives like earlyoom, its use of modern Linux PSI metrics for accurate memory pressure detection, and its reliability through features like page locking to avoid swap. It's a focused, efficient tool that does one job well with minimal system impact.
