Fatal Error: Could not allocate memory: MemoryLabel" DynamicArray

Hello everyone.

Using Unity version [5.5.2f1]
I recently ran into this issue and I have a question. I've recently made some wide sweeping changes to my code. However, the build prior to this one doesn't run into this issue, so I assume the problem lies within my code.

When loading a scene, I get the following error below. When I don't get the error, it takes ages for the scene to load. In addition it seems I'm also losing memory on my machine.

My question is for confirmation of the nature of the error.

- It says memorylabel is a Dynamic Array. Would this mean something in relation to a list or array datatype in my code? This is my assumption.

- I have been combing through my changes searching for a problem area (I normally don't make large changes in one session as it is a headache to test - this scenario being a prime example), however I am just hoping to make sure I am accurately searching the code as I attempt to narrow it down to a specific class instance. Your help would be appreciated!



Just to add. I took another test (this test didn't produce the error above as I loaded a different scene). What is being loaded during a scene change that would or could possibly take so much space? The changes I've made don't necessitate any increase in objects that I can recall. Please see images

Before Scene load (scene has only 1 object - created for this test)



After Scene load (huge difference)



I will add that the last two images AND the ones following are from a test loading to a scene with one object in the scene. As you can see, there is no high script related issues in the images below for this same scene.





Thanks!

 

I believe I have narrowed down the error to my code... and I am working through the possible C# scripts that might contain the issue.

However, if anyone has any thoughts regarding the meaning behind the MemoryLabel: "DynamicArray", that would still be helpful. I will be sure to update the thread once I find the error in case this might be helpful to someone else.

Thanks

 

We are getting a similar error on iOS builds randomly - allegedly trying to allocate gigabytes of memory during scene load. I'm pretty sure this is Unity-related as we have nothing that would allocate such memory dynamically.

 

Here's an example of such crash. I wonder what's on Line:551

Could not allocate memory: System out of memory!

I also came to this. Also submitted a bug report. Is there something to do in the meantime? I'm trying to build asset bundles that are quite large all together.

 

I'm getting a very similar report that i'm confused on:

Trying to allocate: 18446744073694350344B with 16 alignment

Clearly, we don't have an asset that large. I'm running on 2018.2.13f1

 

Same issue: Trying to allocate: 38985230687B with 16 alignment. MemoryLabel: NewDelete

Only on some machine: I'm running 2018.2.17f1

 

Hello!
I get a similar error on Oculus Go (Android). I am loading assets from the server. Assets are scenes that I later load in additive mode. The first loading always goes well, and the second leads to this:

Could not allocate memory: System out of memory!
Trying to allocate: 503464340B with 16 alignment. MemoryLabel: DynamicArray

 

We're starting to see similar errors once we updated from Unity 5.6 to Unity 2019.1.9.

Non-fatal Exception: java.lang.Exception: Error : Could not allocate memory: System out of memory!

Trying to allocate: 18446744072619753546B with 16 alignment. MemoryLabel: String

Allocation happened at: Line:314 in ./Runtime/Core/Containers/StringStorageDefault.h

I am quite certain that we are not trying to create any objects that large. We are using asset bundles quite a bit though.
@Aurimas-Cernius do you have a link to that bug so that we can track its progress?

 

@Aurimas-Cernius I too am interested in knowing more about the bug you mention.

 

For conciseness, was this the issue? https://issuetracker.unity3d.com/is...38.1850701728.1569340467-288991560.1554822249

@Aurimas-Cernius ?

 

Still happening in Unity 2021.3.11f1 EDITOR CRASHES WITH OUT OF MEMORY WHILE IMPORTING ASSETS. Memory Label: Dynamic Array.

When importing, and changing files and folder path from anywhere into the Assets folder in the Unity Editor, and also after deleting the library folder and reopening the project, unity crash with the same crash error.

So we can't even move our assets in the editor!!!
One of my coworkers submitted a bug report.
