MATLAB 2021a Memory bug

Hi, even I did not run any script, the memory usage of MATLAB 2021a, still increasing until 100%, which is definitely a bug, I had reinstall, and same. I tried clear and clc still not work.

The pack function may be a temporary option.

It may be appropriate to Contact Support and tell MathWorks about your problems.

Do you happen to have the documentation open, doc ? There have been memory bugs in jxhelper

[Dianxin]

You mean open the .m or .mat files? No, I did not. I closed MATLAB and reopen it. By monitoring the memory usage, it still increases and no additional seesion is open as shown in the diagram. It is so weird.

Can I ask if theres memory bugs in jxhelper what should I do? I tried google but did not found a solution.

Thanks a lot!

Yes, I did submit the problem to MATLAB support, it is so weird, I am not sure am I the only person who had the problem.

Ah, the proper name is jxbrowser not jxhelper

I think it is not this bug, I tried to clear all but the memory usage still not decrease which is weird. I am not sure am I the only person who have the problem.

Did you experiment with switching to HTML rendering?

[Dianxin]

No, I think the problem got solved, I installed 2021a again and at this time I clicked yes for sending experience or report to MATLAB for enhancing user experience or something, and it seems solved.

[Nihar Sabnis]

I have the same bug and for me, reinstalling with report to MATLAB for enhancing user experience option does not seem to work. Any thoughts?

[Dianxin]

I remembered that I did for 3 times, so I know it's not a good suggestion but it worth an another try. gooooooooood luck! :)

[Don La Piana]

Mine wasn’t a memory issue. But pls keep those thoughts coming. And you do send.

[Dianxin]
