How do I know if my crashes are out-of-memory crashes?

Look at the device and memory context of your crashes, out-of-memory crashes cluster on low-memory devices and often correlate with longer sessions or memory-heavy moments. If you capture crashes with device model, available memory, and session context, an out-of-memory problem shows a clear pattern: the crashes concentrate on devices with less RAM, and may increase the longer players play (indicating a leak) or spike at memory-intensive points like loading large areas. Crashes that hit low-end and older devices far more than flagships are a strong out-of-memory signal. Without that context, out-of-memory crashes can masquerade as random; with it, the memory pattern is usually unmistakable and points you straight at reducing footprint or fixing a leak.

What's the difference between a memory leak and just using too much memory?

Using too much memory is a baseline footprint problem, your game's steady-state usage exceeds what the device has, so it can crash even right after launch on a low-memory device; the fix is reducing your overall footprint to fit the weakest target. A memory leak is a growth problem, your game allocates memory it never frees, so usage climbs over time during a session until it eventually crosses the limit and crashes; the fix is finding and releasing the leaked allocations. They show different crash signatures: a footprint problem crashes low-memory devices quickly and consistently, while a leak crashes after extended play as usage creeps up. Both cause out-of-memory crashes, so preventing them fully means addressing both, capturing crashes with memory and session context helps you tell which you're dealing with.

How to Prevent Out-of-Memory Crashes

Q: How do I prevent out-of-memory crashes?

Attack both the baseline footprint and the leaks. Keep your memory footprint within the limits of the weakest device you support, budget for low-end targets, optimize assets and textures, and load only what you need, since an out-of-memory crash is fundamentally your game asking for more memory than the device has. Find and fix memory leaks, where allocated memory is never freed so usage climbs over time until it crosses the limit, a game stable at launch but crashing after extended play is a classic leak. And capture crashes with memory and device context so you can confirm crashes are clustering on low-memory devices and target footprint reduction rather than the wrong cause. Out-of-memory is a leading crash cause on mobile and low-end hardware, and these steps address it at the source.

Quick answer: Keep your footprint within your weakest target's limits, find and fix memory leaks, and capture crashes with memory and device context. Out-of-memory is a leading crash cause on mobile and low-end hardware.

Out-of-memory crashes are among the most common on mobile and low-end hardware, the device runs out of memory and the OS kills your game or it crashes outright. Preventing them is about footprint and leaks. Here's how to prevent out-of-memory crashes.

Keep Your Footprint Within Your Weakest Target's Limits

An out-of-memory crash happens when your game asks for more memory than the device has, so the core prevention is keeping your footprint within the limits of the weakest device you support. Budget memory for low-end targets, optimize assets and textures, and load only what you need, since a footprint that's fine on your machine can blow past a modest device's limit.

Bugnet captures crashes with device and memory context, so you can see which devices are running out of memory. Sizing your footprint for the weakest target prevents out-of-memory crashes at the source, because the crash is fundamentally a footprint-versus-capacity problem.

Find and Fix Memory Leaks

Many out-of-memory crashes come from leaks, memory that's allocated but never freed, so usage climbs over time until it crosses the limit and crashes. So find and fix leaks: a game that's stable at launch but crashes after extended play is a classic leak signature. Fixing leaks prevents the slow-creep out-of-memory crashes.

Bugnet captures crashes with context including session length, so leak-driven crashes (which appear after longer play) are identifiable. Fixing memory leaks prevents the out-of-memory crashes that don't show up immediately but accumulate during a session until the device runs out.

Capture Crashes With Memory and Device Context

You can't prevent what you can't see, so capture crashes with memory and device context. When crashes cluster on low-memory devices, that's your signal it's an out-of-memory problem, pointing you at reducing footprint rather than chasing the wrong cause, so you can prevent the recurrence.

Bugnet captures device and memory context with crashes, surfacing out-of-memory patterns clearly. So prevent out-of-memory crashes by sizing your footprint for your weakest target, fixing memory leaks, and capturing crashes with memory context, addressing both the baseline footprint and the leaks that push devices over the edge.

Keep your footprint within your weakest target's limits, find and fix memory leaks, and capture crashes with memory and device context. Out-of-memory comes from baseline footprint plus leaks, so address both.
