Application crashing due to libcef memory access violation #23

Open vkomperla opened 2 years ago

vkomperla commented 2 years ago

Our application is crashing repeatedly, and the CPU utilization has increased drastically. There are no exceptions being generated but we were able to obtain a crash dump and observed the following error:

_In w3wpStCoTrPID1184Date05_30_2022Time_03_21_46AM384Second_Chance_Exception_C0000005 (1) (2).dmp the assembly instruction at libcef!cef_string_utf16_toupper+afe15 in C:\home\site\wwwroot\runtimes\win-x64 \native\libcef.dll has caused an access violation exception (0xC0000005) when trying to read from memory location 0x00000020 on thread 41

The application initializes Ironpdf dependencies on startup by generating a pdf from html as a background operation.

We noticed that redeploying the application fixes the issue, and on redeploying a second time, the issue arises again.

We would like to understand what libcef is, how it is used in IronPDF and how to stop this issue from occurring.

Application environment details: Package: IronPdf Package version: 2021.12.4495 Platform: Azure App Service OS: Windows .NET version: .NET Core 3.1
