Random Crashes :-(

Post by hplighting » Sun Dec 18, 2016 3:12 pm

My Setup:
OS: Windows 10 x64
CPU: Intel Core i5
RAM: 8GB

Enntec PRO USB --> DMX
AKAI LPD8 USB MIDI Interface

When using QLC+ it seems to just randomly crash sometimes for no explainable reason. I'm currently using the latest version of the software although I've had the issue with previous versions as well as when using different computers .
The computer can be running for hours working fine and then suddenly it comes up with not responding which is quite awkward i the middle of a show :oops: To fix this I have to force close QLC and then reopen it and its back up and running ! any help with this would be appreciated as I can't carry on with this.
Please let me know if any other info is needed to help fix this - thanks for your time :-)

I'm running into a very similar issue sporadically. QLC will be running, but after an hour or two it'll stop responding. I force-close the application, but in my case re-launching QLC+ brings up the window but the contents are never populated and after clicking around I get the not responding message again. I tried logging out of my account completely and re-logging in, but the same thing happens. Ultimately, I have to restart the computer and then QLC+ will open and operate normally.

This has happened at least 3 times since updating to 4.10.5b (about 3 weeks). We've been using QLC+ for roughly 2 years and I don't recall this issue ever happening prior to to installing 4.10.5b.

My specs are very similar:
OS: Win10 x64
CPU: Intel Core i5
RAM: 8GB

DMXKing Ultra DMX Micro
4 x Chauvet COLORado 1-Quad Tour

Functions:
1 x Chaser Function
20 x Scenes

Hopefully someone will be able to help because I can't keep using the software with it crashing mid way through performances. It sounds like you have a slightly different issue because I only have to restart QLC to get it back - hopefully both issues are resolved :-)

Happened to me too last night....luckily enough on exactly the last note of the gig :D !
I got a few clues on what causes it after 3-4 times it crashed in the middle of a performance:
(Akai APC mini // i3 Windows 10 Asus laptop // running QLC+ 4.10.5b // Work LM3 usb-Artnet interface )

Probable Causes:

- Fast slider input -and/or- multiple slider movement simultaneously
- Running matrix FX on multi-head fixtures (ie led bars) + dimming them on a slider
- Simultaneously running dual dimmer packs (ie 6+6 packs ) + moving or other mixed LED fixture types
- Pluging the APC mini on my single USB 3.0 port ( never crashed when plugged to other ports on the laptop )

Those are just clues, another probable cause could be lack of processing power on my laptop but i see many arduino or other lesser machines do the job...
btw i only need to restart QLC+, not windows to get it running again

I wonder if it could have something to do with fast slider inputs?
I've had mine crash before when I was doing loads of quick inputs on a MIDI pad?

Yep .... CONFIRMED
did some testing on 3 pc's
it's rapid slider movement that does it
(jerking a slider fast or using many simultaneously, both with and without the artnet interface)

When you unplug the akai and plug in again and restart qlc the freeze problem is gone. That's why I make it crash with fast slider movements before the show ;)

Hello everybody,

We have had the exact problems as you, we have had during our last two live concerts freezing, during the performance. We never had this problem before, using the old version of 4.8.5 qlc. We are very hesitant to continue using this new version during our live concerts, as we can not permit blackouts when re starting the system.While waiting for a solution to this problem, we are going back to the old version 4.8.5. We hope a solution can be found, as we really like the new version.

Thank you...the show must go on

Have you guys checked this thread and tested the test versions ? viewtopic.php?f=32&t=10757

I understand there is something specific to Windows about fast slider movements, but if I spend some time to investigate about it, I need exactly what to look at, otherwise it's a waste of my time.
So, can you please tell me how to reproduce the issue with a very simple project ?

If I connect a APC Mini to let's say 5 sliders in level mode, will I be able to reproduce the crash ? How many channels should I be controlling ? 1 ? 10 ? 100 ?
Should I have a DMX adapter connected as well, or it doesn't make any difference ?

In other words: the more details, the higher chance to get it resolved.

Hello,

I did the test with QLC+_4.10.6.210.exe in the theater where i work. After 15 minutes it crashed.
Then I tested the QLC+_4.10.6.153.exe and tested for about an hour no chrash. We will be doing a rehearsal this afternoon for 3 hours, will keep you posted if there are no crashes...

Thank you so very much for your help.

JD
