Q Light Controller+

Hello,

I am testing using version 20190217, using the image sent to me after making the donation. My use case is to have chasers running 24/7, with only RGB LEDs and no other fixtures.

When using a chaser that loops through multiple scenes, I find that the loop runs fine as long as there is no fade-in/fade-out between scenes. However, when using fade-in and/or fade-out functionality, I notice that the qlcplus binary crashes on the RPi after a few hours of operation. I also noticed that the %CPU used by qlcplus increases over time, until it eventually crashes. The CPU% is stable when there are no faders and the program does not crash. Perhaps this is unrelated and normal for faders? I see %CPU go up to 300% at times.

I ran the qlcplus binary with gdb to troubleshoot further. Attached below is the output from the crash after a few hours of running a chaser with faders.


I hope you can provide some help to resolve this issue. Please let me know if I can provide any clarification and/or more information regarding the issue. Looking forward to hearing back from you, thanks in advance!

Can you please provide your project file so that I can do some tests with it?

For sure, it is attached below. Of the two chasers in the project, the one named "Rainbow" works fine, but the one called "Rainbow Fade" crashes after a while (and increases %CPU steadily).

Thanks for the project but wait! Latest image is 20190825.
You should have received an email with the download links.
Please check cause that might solve your situation. I am testing your project with the latest QLC+ and I don't see leaks or increase in resource usage.

Ah, I started working on this project before the latest image was released! I will try it out on the newest version and let you know! Thanks!

Hey mcallegari,

I tested with the latest version and am no longer having this issue. Thanks a lot!
