Memory Leak Hunt Agent

A confirmed memory leak cause, a fix tested by repeat runs, and memory staying flat across a long session

Memory Leak Hunt Agent: what goes in, what the agent does and what you get

What it does

A game or web app runs fine for ten minutes and then crawls after two hours, and the profiler shows a wall of objects. This agent runs a scripted session that repeats the same actions, such as opening and closing a menu or loading and leaving a level, and takes memory snapshots at set intervals. It compares the snapshots to find object types whose counts keep growing, then narrows suspects by tracing what holds on to them, such as an event listener never removed or a cache without a limit. It proposes a likely cause for the developer to test. After each fix it reruns the same session and compares growth, repeating until memory stays flat within the allowance. The developer approves each code change. Edge case: memory that grows for the first 5 minutes and then plateaus is treated as warm-up, not a leak.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

  4. Does growth continue steadily after warm-up?If not: Lengthen the session or script the leaking action more heavily and snapshot again. Back to step 2.
  5. Trace what holds on to the growing objects
  6. Name the likely cause and propose a code change
  7. Developer approves the code changeThe agent waits here for your OK.
  8. Rerun the same session with the change and take snapshots

How it decides

It treats an object type as leaking when its count grows steadily across at least 5 snapshots after warm-up, and it accepts a fix only when growth falls below the allowance in a repeat run.

  • Ignore the first 5 minutes or first 3 snapshots as warm-up
  • Treat growth above 1 MB per 10 minutes as a leak
  • Test one suspect at a time
  • Stop after 4 suspects and ask the developer for direction

Make it yours

Every agent is a starting point. You choose these settings for your own situation.

  • Session script and snapshot interval
  • Growth allowance (default 1 MB per 10 minutes)
  • Warm-up length
  • Profiling tool
  • Maximum suspects to test

What keeps you in control

It always asks you first

  • Developer approves each code change before it is run

Hard limits

  • Never change code without approval
  • Always run tests against the same script for fair comparison

It stops when

  • Done: Repeat runs show memory flat within the allowance
  • Stop: No suspect explains the growth after 4 attempts, so the agent hands the snapshot findings to the developer

An example run

What happensA 90 minute session grows from 410 to 1,100 MB. Snapshots show 'MenuEntry' objects growing by 1,200 per 10 minutes, held by an event listener on the inventory screen. The agent proposes removing the listener on close. A rerun shows 410 to 452 MB, plateauing. The developer approves the change, and a second run confirms.
