Game rendering freezes randomly at runtime

Hi.

I have been developing a game and deploying to windows phone. But
after running the game (device) for a while the rendering stops (no crash exit app) and stays stuck on the same frame.

How can I go about solving this?

dump file from phone - Eception code 0xC0000194

unity 5.3.0f4, wp universal 8.1, vs 2015 update 1

debug:
http://clip2net.com/s/3tpAJ6X

Unhandled exception at 0x70C58F0F (qcdx9um8960.dll) in babushka.exe: 0xC0000005: Access violation reading location 0x13C0C03C.

develop console in device - 3 or 4: Odd tag in Cleanup before freezing
unity editor - no error

Thanks!

 

sorry my version - 5.3.0f4

 

version 5.3.1.f4 - not work (Odd tag in Cleanup)

 

I have determined that due to an error occurs:

I have Canvas(World Space) http://clip2net.com/s/3tpWCMC
I have an Image (Canvas): http://clip2net.com/s/3tpWEyJ

On it hangs a script that changes the fillAmount (Update script) http://clip2net.com/s/3tpWHfm

- wp 8.1 error Odd tag in Cleanup. ^(

if Canvas(ScreenSpace) - all right

Is there a solution?

 

Hi Tomas, Was a bug report ever submitted for this? I think I may be encountering the same issue and it would great to get it fixed

 

on a blank project has not yet happened again. But I'm pretty sure that the problem was in the Canvas, the issue in the conditions

 

I have found the same thing. I have created a demo app with just a slider in it on a canvas set to world space and I can update it without it freezing. Its very frustrating, the worst part is that the game only appears to freeze when I am running the app on my windows phone after I have deployed it (ie when its not connected to my pc so there is seemingly no way of knowing what the error is)

 

As I am unable to reproduce this in a demo app would be acceptable to attach my entire game to the bug report?

I have been unable to get any concrete error message apart from this

Odd tag in Cleanup!
(Filename: C:/buildslave/unity/build/Runtime/Jobs/Internal/JobQueue.cpp Line: 1115)

 

I have logged a bug report (I had to attach the full project)
Case number 768068

 

Hey guys,

I'm getting the same bug in Unity 5.3.2p2 and p3. The game either freezes or crashes with an error:

"d3d11: failed to lock vertex buffer 092D6D04 of size 4194304 [0x8007000E]."

Is there any chance this bug is going to be fixed or should we revert to some of the previous Unity releases?

Cheers,
Tom

 

Tomas,

Should I add Tom's comments to the bug I logged (768068) or should this issue be logged separately?

Thanks
Matt

 

Tom,

I'm just wondering if your having the same symptoms as me.

Does the game crash for you in the editor or when deployed to a windows device (or both)

Can you reproduce the crash / always make it happen - in my case the freezing occurs at a seemingly random point.

 

The same thing was happening to me for the past few days - the game works good on a Windows 8.1 Laptop and Tablet, but freezes randomly on all Windows Phones (8.1)- Lumia 925 and Lumia 520. The freeze does not cause any errors or breaks when debugging, it sometimes gives the error of "unity d3d11: failed to lock vertex buffer".

Anyway, I updated Unity to the newest version and now I can't even build an empty project. Super frustrating if you already have the game on the market and you want to fix a few bugs.

Cheers,
Tom

 

The start of this thread suggests it may have something to do with sliders. Do you have any in your game?

I created a small demo app, recreating how I use the sliders and annoying it worked fine.

I have been trying to narrow down what causes the issue but not had any luck so far.

The bug I entered has not had any updates - not sure if this means its being worked on or ignored

 

No we don't have any sliders :/. The bug was most likely ignored... Maybe try pinging the person who told you to report it?

Cheers,
Tom

 

What does it mean processed? Does it mean that someone is actually working on it or does it mean that you know about it and it will be fixed in the future?

Any advice which previous Unity version to use before this bug is fixed?

Cheers,
Tom

 

It's been two weeks since matt submitted the bug, and they're still trying to reproduce it? Sorry, but that's not really something to be proud about.

Some people using Unity have actual commercial games on the Windows Phone Store and are waiting for this bug to get fixed. If you're not able to get it done, just please tell them that Unity 5.3 doesn't support Windows Phone and tell them which Unity version should they use.

Cheers,
Tom

 

To be fair to them this bug is horrible to try and reproduce. The only guidance I could give was "Play the game for at least 5 minutes" The 'randomness' of the crash really doesn't help. I wish I could have found the exact action that causes the game to crash but I suspect its something happening being the scenes that I have no control over.

Tom, if you can always get your game to crash with a certain action or after a certain amount of time maybe you could also submit a bug report?

It would be great to have this fixed as soon as possible, I guess if we all work together that will happen quicker.

*Inspirational speech over*

 

Hey matt,

I managed to get rid of it:

• I reverted the project to Unity 5.2.4f1 (remember to delete all the folders beside Assets and Project Settings)
• I unchecked the "Unity C# Projects" in Build Settings
• I have set some of my plugins DLLs to "Don't process".

Please let me know if you managed to succeed. Thanks!

Cheers,
Tom

 

Interestingly version 5.2.4 was the last version I installed before updating to 5.3.

The reason I updated to the latest version was to try out the unified In app purchase. However, the documentation for windows store was few and far between so in the end I took out all of my IAP logic (as previously I only support IAP for Phone 8 builds which are not supported in the latest version (8.1 minimum))

I have respond to the request for further information from the QA team regarding the bug so ill give it another week before going back to an older version.

 

This issue has affected numerous Unity users. Numerous bug reports and threads have been created by people having an "Odd tag in cleanup" error. All of the bug reports are being closed as "non reproducable" by Unity QA.
So myself, and other members are being very confused as to why all of theese bug reports are being tagged as "non-reporducable".

It would be greatly appreciated if a developer from Unity please glance at the bug reports and some forum posts to figure out what is going on here? Why are the repros not being reporducable by Unity QA, but yet other unity users are able to re-produce the problem from reporos that are made publicly available via dropbox?

This has become very frustraing for me to deal with this error that is occur. Here is a list of links most likely related to the same issue, so you can see this is not an isolate issue that has been occuring.
It appears the error is prominent on AMD A-series processors, and mainly non-Intel i CPUs according to observing the hardware which the error occurs on.
(Note that the bug links were made availible the by Unity users).

I have downloaded the latest patch Patch 5.3.3p2 and after a short amount of testing my game no longer appears to freeze. I wonder if this is somehow linked to the interesting issue regarding performance when using landscape orientation which has been discussed in a separate thread. (The fix for which is included in the patch)

 

Any updates on this @TTTTTa?

 

Annoyingly this issue has now come back for me. The game always freezes on my Lumia 925 running an insider build version of Windows 10 mobile but the same build of my game does not crash on my Windows 10 tablet (running a full (desktop) release version of Windows 10) Strangely the game doesn't freeze on my Lumia 925 if I run it in Debug mode. It only crashes in the master configuration and there is no log file created on the phone. So now I have no way of identifying the issue / error message

 

ok just to be clear here,

When you say Debugger attached do you mean deploying the game from Visual studio while the Phone is connected?

I have tried this and its when I found the game crashes using the master config but not the debug config (which would give me more information I guess)

When you say go back to main menu after the crash within 10 seconds is that the tile home screen on the phone?

Where would the crash dump be saved to on windows phone 10?

Thanks
Matt

 

Hi Tautvydas, Thanks for the suggestions I have followed them and found the following

After setting the project to Native only I was able to reproduce the crash while debugging but when I hit the Break all button visual studio was looking for a file/dll called memset.i It didn't show me where the crash was coming from

From looking around online this appears to be a C++ reference or file. Im new to this kind of level of debugging so would you know where this file is likely to be stored. Do I need to install a C++ sdk or something like that?

After this I set my phone up to create the dump file and got the following error code 0xC0000194. Again from looking online there was no clear answer on what the error was or what could be causing it. Have you seen this before.

I can paste the rest of the dump file if needed but it just looks like the modules that were loaded at the time - no stack trace

Thanks
Matt

 

I will try the cancel method and let you know how it goes

Here is the dump file summary - If you need the file itself I will have to copy it to my dropbox account - its 257mb

I can reproduce it all the time on my Lumia 925 (running windows 10 insider build (10.0.10586.218))

1.Launch the game
2. Load tutorial level (If its the first time of playing a dialog pops up telling you the tutorial will be loaded, other wise it can be loaded using the bottom left menu. Expand it out and click on the student icon)
3.Once the tutorial level is loaded keep pressing the pause button.
4. I would say doing this for maybe 10 seconds causes the game to crash.

If not going back to the main menu and then back to the tutorial and repeating the above steps causes the crash.

However, here is the complicated part, I first thought the crash came about from me updating unity (I updated in January after about 2 months of not updating - sorry I don't remember exact version numbers)

It was at this time that I updated my Windows Phone to Windows 10.


I have tried the game on the following devices

Lumia 930 running Windows Phone 8.1 - No crash using the steps above
Lumia 950 running Windows Phone 10 (Official build not insider preview build) - No crash using the steps above

Lumia 925 running windows 10 insider build (10.0.10586.218) - Crash


I have not made any massive changes since I submitted the bug so I think that version should still be ok for testing.

 

Guys any updates i am using Unity 5.3.4f1 and Unity 5.3.4p4 and game freezes randomly on lumia 925 windows phone 10 and windows phone 8.1 no crash no exceptions nothing just freeze. sound is playing with no problem

 

Same problem over here, updated to 5.3.4f1 some days ago and it's still happening.

Just installed 5.4.0b16 and... still freezing...

It only happens on my phone (Lumia 520, WP8.1), but only on non-development builds (though a few days ago it did happen in a dev build, but only once).

After reading #7, i disabled a canvas i had set to <Screen Space - Camera>, and ran the game 5 times in a row, with no freezes at all. So that must have been the cause of the problem (at least for me).

Since my canvas only contained an image (which had to fill the entire screen without losing its aspect ratio), i can achieve a similar effect using a sprite renderer and some code.

However, i will try to make a minimal repro project. If i can reproduce it with success, expect to see my bug report soon...

UPDATE: Sadly, i couldn't reproduce it in an empty project, there must be something more...
UPDATE 2: Now it's freezing on the title screen, it didn't happen before. The only canvas there is rendered on Screen Space - Overlay, so it should be something else. No freezes in-game since i removed the canvas there though. Weird...

Also, it's probably hardware specific, as it's happening on my sister's 520 too, but not on my friend's 930

 

@Tautvydas Did you have any luck with the dump file debugging it locally?

If you would like the latest build to test against I can happily provide that - Should I update my bug or log another one?

I now have solid steps to reproduce but it does seem to be device specific.

For me is always crashing on my Lumia 925 but never on the 930 or 950

I am also now finding that the game only crashes when using the Master configuration.

 

Watching this thread for a month. Same problem - freezes without crashes. Since I already published game, I can share some info. At least these devices has freezes:
Nokia Lumia 625 - Win 10
Nokia Lumia 925 - WP8.1
HTC 8S - WP8.1

 

I am also having random freeze problems on the Nokia Lumia 620 (WIN 10).
