Modded Minecraft can chew through gigabytes of RAM without warning, and tracking down the culprit is rarely straightforward. Calm The Leaks Mod works alongside All The Leaks (ATL) to cut through the noise — filtering false positives, ranking leak reports by confidence level, and pointing you toward the mods most likely responsible. If you run heavy modpacks and dread the slow creep of memory usage, this is the diagnostic companion worth adding to your toolkit.
Key Features
- Smart False-Positive Filtering — Intercepts ATL leak reports and automatically suppresses startup noise and stable chunk retention alerts that would otherwise clutter your results.
- Confidence-Based Leak Reports — Instead of dumping raw data, the mod provides explanations and confidence levels so you can prioritize real leaks over harmless fluctuations.
- Trend Tracking & Culprit Identification — Monitors leak growth over time and identifies the mods most likely causing memory issues, saving you hours of manual profiling.
- Automatic Spark Integration — Auto-triggers Spark profiling sessions when a significant leak is detected, giving you deeper analysis without extra steps.
- In-Game Commands — Use
/ctl statusto check current memory health,/ctl leaksto view active leak reports, and/ctl explainfor detailed breakdowns of flagged issues.
