Hi,

We are experiencing many crashes with PB2019 R3 Build 2703.

All are related to libcef.dll

This is happening in both development environment , Windows Server 2019, and also on our production environment,  Windows Server 2012.

The crashes seem to be random, I can't find any specific action or event that is causing.

Following is the event viewer log from our development platform: 

Faulting application name: PB190.exe, version: 19.2.0.2703, time stamp: 0x6065b6d0
Faulting module name: libcef.dll, version: 3.3626.1894.0, time stamp: 0x5c591850
Exception code: 0xc0000005
Fault offset: 0x0028bb3a
Faulting process id: 0x8364
Faulting application start time: 0x01d7683112755e67
Faulting application path: C:\Program Files (x86)\Appeon\PowerBuilder 19.0\PB190.exe

Report Id: 05878b6d-b058-46ea-9166-13a340813b3d

From our production server :

Faulting application start time: 0x01d768c405ec170e
Faulting application path: C:\Program Files\CareProg\MediCare\3\medical.exe
Faulting module path: C:\Program Files (x86)\Appeon\Shared\PowerBuilder\pbcef\libcef.dll
Report Id: 828bcad6-d4b8-11eb-8352-00155d0a092b

 

Any help would be appreciated in resolving this.

TIA

Thank you for that information.

In fact we added a webbrowser control to one of our windows, so atleast I can disable it till we find what the problem is.

Anyone else encountered this crash?

Hi Mickey,



we also use this new webbrowser control to show a page with the 'Openlayers' library. Our customers uses this windows (with the webbrowser control) al lot and are complaining that it sporadicly crashes (sometimes a few times a day). We can't simulate it in-house so i have no idea what is causing this crash.



In the event-viewer of the customer, i saw the same output from the crash (libcef.dll).



i noticed that the version noted (3.3626.1894.0) looks like a build from 2019. I don't know if there are any plans to upgrade this version?

Hi Mickey,

I had the use of CEF crashing my application when closing the app (only on windows server 2012 R2) and there's a workaround.

Hi Mickey;

   FYI: Please note that the PB IDE is not certified for use with any MS-Windows "server" editions. In your case W2019.

http://docs.appeon.com/pb2019r3/release_bulletin_for_pb/system_requirements.html

  App EXE's built from the IDE though are Windows "Server" capable.

Regards ... Chris

Hi Mickey,

I think libcef.dll is part of the WebBrowser control.

Maybe this helps you to find out what could be the reason.
