What causes an out-of-memory crash?

The game asked for more memory than was available — either a leak that grows usage until it fails, or a peak load (large assets, too much loaded at once) that exceeds the budget.

How do I catch this when it only happens for some players?

Capture it automatically from the player's device with the full stack trace, the device and OS, the build, and a breadcrumb trail of what they did. That turns a vague complaint into a specific, reproducible issue you can fix without owning the hardware it happens on.

How to Fix an Out-of-Memory Crash in a Game

Quick answer: Profile memory to see whether it grows over time (a leak) or spikes at a moment (a peak), then fix the leak or reduce the peak by compressing assets and loading on demand.

An out-of-memory crash is either a leak (memory climbs until it fails) or a peak (a moment that needs too much). Profiling tells you which, and they have different fixes. Here is how.

How to fix it

1. Profile to classify it

Watch memory over a session. A steady climb to the crash means a leak; a sudden spike at a specific moment means a peak load. The shape of the curve tells you which problem you have.

2. Fix a leak

If memory grows and never drops, something is retained that should be freed — unreleased assets, growing caches, listeners holding objects. Trace what climbs and release it on the right lifecycle event.

3. Reduce a peak

If it spikes at a load or a busy scene, you need less resident at once. Compress and right-size assets, stream content instead of loading everything, and unload the previous area before loading the next.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every your game error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

The errors you never hear about are the ones quietly costing you players. Visibility turns them into a worklist.
