Webgl, Out of memory After a long time

Unity Engine
1

Hello everyone I have a problem with Out of memory. The application works stably and generates such an error after some time.
Textures on models have a native resolution of 512x512px, no dynamic shadows, no smoothing edges. After running the application takes about 97MB Webgl Memory, after some time it throws me anyway a memory problem.

Below screenshot from the console

Can you help me?

There must be something in your code that add to the memory while the application is running.
That could be a problem of garbage collection… you can resolve that in two ways:

  • reload the scene (everytime you do that the memory is cleaned)
  • try with System.GC.Collect(), as far as I know, this command is now supported even in WebGL, but I don’t know since which versions ( @Marco-Trivellato can help explaining that! ^_^)

GC.Collect() is supported as of 5.6
Though, it’s behavior is slightly different compared to other platform: the garbage collection won’t happen immediately, instead it will be postponed to the beginning of the next frame. Good enough for most use-cases, I think.

as @DudoTheStampede mentioned, that seems to be a problem with your code since you are running out of memory inside the Unity Heap. I suggest you launch your content with the profiler attached and take a look at memory consumption in the profiler.

Hi, thanks for the reply.
The problem with the memory I wrote appears when the context is lost.
Is there any way to restore a lost context?

I add that I have updated the unity to the latest version and tested it on linux and the chromium browser.
