when loading level, my game crash, with log like this:

Adreno-GSL: : sharedmem_gpumem_alloc: mmap failed errno 12 Out of memory

Adreno-GSL: : ioctl_kgsl_sharedmem_alloc: FATAL ERROR : (null)

UE4: Ensure condition failed: Creations == Deletions [File:E:\Engine_Svn\4.14.0\Engine\Source\Runtime\Engine\Private\Slate\DebugCanvas.cpp] [Line: 19]

UE4: FProxyCounter::~FProxyCounter has a mismatch. 1560 creations != 1559 deletions

libc: Fatal signal 11 (SIGSEGV) at 0x0000000c (code=1), thread 17315 (main)

i dont know how to fix it, what the “FProxyCounter::~FProxyCounter has a mismatch. 1560 creations != 1559 deletions” means? is there any suggestion?

Hi,

Can you upload your entire log ? So we can take a look at it ?

Thanks

It looks as though your device is running out of shared memory. I would suggest making sure that your project is optimized for mobile development. I’d also open up the log and type in ‘warning’ in the search bar and try to resolve those issues with your animation instance class, the widget and the other warnings/errors you may find. The warnings could be causing part of your memory failure on the device.

You might need to upgrade some drivers on your device, or perhaps the version of Android - depending on how high Android can be updated for your specific device.

Do you have any images, textures, materials that are of large size that you could possibly size down? Any sort of graphics that would be hard for a mobile device to process?

Review the documentation below, it may help you size down the resources needed for your project.
