Mac Crashing every hour or so using QLC+

[tonymoore]

Hi

I couldn't see a specific forum for this problem so apologies if this is the wrong place, all though I getting this problem as I am setting up a show using virtual conole

I have a macbook pro retina mid 2014 - 8gb Memory Running Big Sur and the latest build of QLC+

All is fine - and then, for no reason the computer just suddenly crashes.

This is the error report

Does anyone have any ideas what causes this? (I can see that QLC is called at as part pf this system crash report)

Thanks in advance
All the best
Tony

Memory leak inside a QLC+ process -> what version do you use? Latest?

[tonymoore]

yes...Latest version

Thanks for the reply
Tony

[GGGss]

yes...Latest version

Thanks for the reply
Tony

Please quote __exact__ version + build number.
And also, upload your project here so things can be checked.

[tonymoore]

Please can you tell me where I find a build number - All the ABOUT screen says is 4.12.6
File attached
Thank you

[tonymoore]

It just crashed again and I lost half an hours work !! - Is there anyway of instigating an Auto Save function, whilst this bug still occurs that would be a life saver - It's not always easy to remember to keep saving every change you make as you go along

Thank you

[GGGss]

ehhm ... your project makes QLC+ crash on opening. This means something is fishy...
Let's have a look -> clearing the interface from universe 1 let's me open your project.
Except that Hopium1 and Blue 2 share the same functionality (meaning inside a soloframe that they do cancel them bilateral), I can't see to find any problems.
I'm on PC - so this might not be a fair test.

[tonymoore]

Thanks for the feedback - I will look at those two scenes/buttons and see if that makes any difference - is possibly a bug that Universe 1, once assigned to a specific USB DMX device, crashes nothing is connected?

[Solander]

Did you find a solution for this? I also have version 4.12.6 and my mac (MacBook Pro Mid 2015, Big Sur) keeps crashing. :/
I've included my project as well.

[GGGss]

Svart,

Never use the mix of an universe for in & outputs.
I see in universe 1 you have Artnet in and DMX out ... this potential leads to internal buffer over runs.
You are not limited in any way to use QLC+ universes, so split in & output to its own universe.

[Solander]

Fredje,
Thank you! I don't use the input so I've disabled it now. Hopefully it helps!
I'll let you know if it keeps crashing.

[Solander]

Just crashed again. Now I've downgraded to 4.12.5 and hopefully it's more stable.

[Solander]

Another crash... Unusable at the moment.

[sbenejam]

Solander, can you try QLC+ with a simple project and confirm that QLC+ stills crashing. Can you explain how you use this project?. Can you explain how you plays this project during the show. QLC+ crashes when you click on a certain button?. The crashes occurs when you are editing, scenes or functions?.
I'm testing your project on Ubuntu 22.04 and I don't have any issues when using the buttons to activate scenes.

[Solander]

sbenejam,
I didn't do any changes when it crashed. Just set intensity and color on 10 different fixtures, and let them be. After maybe 10-30 minutes the computer just displayed error screen and rebooted. I had about the same error dump as the author of the thread.

I've downgraded to version 4.12.3 and now I've no issues with crashing. The show is really simple so I will stick with this version for now.


When I have time, I will try it with a simpler project. We're in rehearsing now with premiere on Friday.

sbenejam,
After maybe 10-30 minutes the computer just displayed error screen and rebooted. I had about the same error dump as the author of the thread.

So your problem does nothing have to do with QLC+. It's your system (!)
QLC+ crashes quietly and disappears, but your system is still up and running. You can restart QLC+ afterward with no problems.
This is not the case with you, so something else plays along.

I've downgraded to version 4.12.3 and now I've no issues with crashing. The show is really simple so I will stick with this version for now.

Wasn't 12.3 the version before multi-threading was introduced?
This could explain why your system keeps running. The cores of your processor aren't under stress now. I would start being skeptical about your hardware if you use it in productions...

When I have time, I will try it with a simpler project. We're in rehearsing now with premiere on Friday.

Your project __is__ simple. Don't worry about this. You don't have EFX running, nor RGB panels, nor animations. These are the CPU intensive blocks of QLC+. I would have it run on a Raspberry Pi 3.

[musicmand]

Was there ever a solution to this problem? I'm working my way through this now... Updating fixture definitions, isolating universes to one input or output... I just need it to be stable.

[ConnyGoat]

I had the same problem this weekend, got the same error and reboot.

I had everything in one universe, midi in and dmx out. Qlc was taking like 80% of the cpu.

I have now separate it, and qlc wont take more than 30% for now, i tested it yesterday and didnt reboot.
Also it did reboot when i was programming the midi, only playback seems ok for now.
