ortools crashes ucrtbase.dll

[Attila Peller]

Hi,

 

I have a QGis plugin to solve a vehicle routing problem using ORTools. 

 

When the program gets to the ORTools part, Qgis crashes and leaves an Error Event (attached) in Eventviewer, but no stacktrace.  

 

According to this event the crash is caused by ucrtbase.dll. See the screenshot below.

 

The OS is Windows server 2012 with latest updates.

 

I have created the user mode crash dump which is uploaded to onedrive including the WER report file here:

Any help would be appreciated!

 

Cheers,

 

Atis

Hi Attila,

Just a tip: I had similar problems when the target machine did not have the right version of the Visual C++ Runtime. This could be a case in your situation since you are using Windows Server 2012 which certainly lacks the latest MSVCRT by default.

Cheers,

Mark

Hi Mark,

I’ve already applied the c runtime from this update:

https://support.microsoft.com/en-us/help/2999226/update-for-universal-c-runtime-in-windows

 

also has all the C++ redistributables installed, but it always crashes when it comes to

routing.SolveWithParameters

What else could be updated/installed??

 

Cheers,

Attila

Can you check all callbacks you pass to the solver are not garbaged out?

You can try adding GC.KeepAlive(callback) at end of the code. I believe being in a server environment, GC is much more aggressive.

Hi Attila,

What Laurent pointed out helped me in a lot of cases.

Can you please clarify what kind of plug-in are you using? Is it open-source?

If you are using a garbage collected language, preserving a reference to the callback functions helps.

Does this issue happen immediately after you call SolveWithParameters or it takes a while to crash?

Cheers,

Mark

Hi Lauren,

I’m programming in python a QGIS plugin. Not quite sure how to add c code there…

Hi Mark,

I’m developing a Qgis plugin in python for a customer to optimise their trucks pickup routes.

Python uses gc, but this problem is not on python level.

Qgis gets little frozen initially after routing.SolveWithParameters then windows tells that QGIS crashed.

This is the event left  behind.

Hi Attila,

Unfortunately, it is a little bit hard to draw any conclusion based on the attached image without a stack trace.

What I would suggest you do is to create a "stand-alone" Python script with the same model and input data and try to evaluate if the problem still persists.

This way you could rule out if the situation arises in the interop layer between Python and Or-tools.

Maybe this sounds trivial and you have already tried it but let me know if that works.

Best regards,

Mark

Hi Mark,

There is no stack trace because the crash happens on the system C runtime library level.

I did save the user level crash dump and the WER report file, just don’t know how to suss out the cause.

The crash dumps are here:  https://1drv.ms/f/s!ApOUFM1sYj1FhRT5NvmpmrWYYWum

I thought of writing a script running in python only, but the program should run under QGis at the end of the day…

Gents,

I’m back with my crash problem with some extra information.

Working on a QGis plugin written in python3 using ortools to solve a vehicle routing problem.

I’ve simplified the tw vehicle routing code temporary to a travelling salesman problem and for my surprise it worked without causing any crashes.

Since we really need routing, increased the number of routes from 1 to 2 without adding any addition resource constrains and the application started crashing again.

Changed the OS too from Windows server to Windows10, but the crash event looks pretty much the same. The C runtime causes the crash.

I’m wondering if anyone has any idea how the number of the routes can cause the c runtime to crash and if there is any way to debug this?

Most likely gc pressure on the callbacks.

Can you check that any python objects passed to the solver outlive the call to solve.

Hi Attila!

Try the following: when you create any callback then put its reference in a collection that is in the global scope i.e. it is referenced and kept alive by the GC during the whole lifetime of your program. This way we can rule out errors caused by the GC collecting callbacks that are still being called in the C++ layer (which is unaware of the lifetime of your Python objects).

If this works it means the error is in the interop layer.

Let me know what happens!

Cheers,

Mark

Qgis crashes with only leaving eventlog behind and a crashdump.

Below is the Windbg analysis results if that helps.

Hi Mark,

My whole code is in python under Qgis. Under callback you mean function like distance or time callback for routing? Apologise for my ignorance, but being a GIS guy, I don’t know much about C++ at all

Cheers,

Attila

[Laurent Perron]

Yes. Although it seems it crashes when the CP module is loading , and not when solving. 

Do you know when it crashes? Can you add logs in your applications to check if you can actually create a RoutingModel?

[Mark Farkas]

Hi Attila,

Yes, distance and time callbacks. Although what Laurent indicated the failure may occur before solving. Your exception indicates a STATUS_STACK_BUFFER_OVERRUN error and that is not what you get when the GC collects your callback. Did you check your RoutingModel if that is created without errors? Btw. I am happy to do a pair programming with you if the code is not confidential when I get back from my holiday. (27th of March)

Also, can you build a standalone Python script without QGis (using the same data as an input but running a pure Python script with no additional dependencies on QGis)

Cheers,

Mark

[Attila Peller]

My last log entry was before the

assignment = routing.SolveWithParameters(search_parameters)

line if this helps…

[Attila Peller]

Hi Mark,

I really appreciate your offer. I will try to build the standalone python application first and let you know how did it go.

I also have to find some other solution to generate the distance matrix, since letting  google to generate one for every routing request,  proves to be too expensive.

[blind.line]

Attila, 

For the distance matrix generation, I’ve had good results using OSRM (https://github.com/Project-OSRM). Certainly not as accurate as Google maps data, but good enough for all cities I’ve tested so far. 

A quick search shows a few qgis osrm plugin projects on github, but the two I glanced at seemed inactive, but maybe one might give you a starting point.
