What problem does it solve?

This Skill helps developers diagnose and fix memory leaks in the Lodestar Ethereum client by capturing and analyzing heap snapshots from running nodes.

Core Features & Use Cases

  • Heap Snapshot Capture: Remotely trigger Lodestar's REST API to write heap dumps for specific threads (main, network, discv5).
  • Snapshot Analysis: Utilize a bundled Node.js script to compare two heap snapshots, highlighting significant growth in object types and counts.
  • Use Case: When a Lodestar beacon node's memory usage is steadily increasing over time, use this Skill to capture heap snapshots before and after a period of activity, then analyze the diff to pinpoint the source of the leak.

Quick Start

Use the lodestar-heapsnapshots skill to capture a heap snapshot from the network thread of a Lodestar node running on 127.0.0.1:9596 and save it to /tmp.
