and some marker load is failed.just like this:

"loadMarker(): Error loading pattern file /marker_120. aframe-ar.js:2 ARToolKitJS(): Unable to set up AR marker."

if i load this html for many time,the number of marker will be change many time. sometimes i got a "out of memory" error。

I checked the chrome memory and found the js VM instance memory is 120MB and JSArrayBufferData is 68%.

I have checked all the issue,and i found the same question but no answer and closed.

can you help me?

If the current behavior is a bug, please provide the steps to reproduce.

What is the expected behavior?

If this is a feature request, what is motivation or use case for changing the behavior?

Please mention other relevant information such as the browser version, Operating System and Device Name

Hi, are you sure all files have the right extension?

"loadMarker(): Error loading pattern file /marker_120.

Did marker_120 has an extension, for example?

thank you for your question. 1.Yes,I sure.when i load 40 markers，the html will be viewed normally.the program is no problem 2.this is main code. <!doctype HTML>

mycode.zip this is my code

I downloaded and ran your code. I see no problems in console of Chrome.

So, what brings to my attention is the if i load this html for many time,the number of marker will be change many time. sometimes i got a "out of memory" error. I think you may have performances problem. Do you have the possibility to run such file on another more powerful computer, or with a powerful smartphone? and maybe see if it shows error too

Thank you for your confirm

my node pc: Intel i7-8550 CPU ,16G RAM,64bit win10 ,128G SSD i also test this program on my friend's pc: Intel i7 CPU，32G RAM,64bit 256 SSD

the error is still there.but we didn't found out of memory anymore.

yesterday evening,when i got your answer ,i tested on my pc,just onetime no error. how about your pc config?

Macbook Pro, 2,6 GHz Intel Core i7, 32 GB memory.

On your HTML I see no error, so strange
