Agent fixed memory leak using PID forensics and source code
dotey · x · 2026-08-26
Sharing how an AI Agent optimized performance by using a screenshot from Activity Monitor. The agent used the PID to run system commands (like vmmap), combining project scale, thread status, and source code for causal localization.
Inference Chain:
- vmmap showed 2.3GB physical footprint, mostly in MALLOCSMALL.
- Ruled out IOSurface and GPU graphics.
- Found 439 threads; source code showed std::thread::spawn for every thumbnail.
- Calculated waveform data for 24,278s at 16kHz mono (1.55GB), matching the peak memory usage.
This demonstrates "system forensics + source verification", achievable via Agent Computer Use.
