    Issue:

     

    I try to start the Web Agent, but it doesn't start properly and Apache reports error :

     

    AH00419: master_main: create child process failed. Exiting.


    Environment:


    Web Agent 12.52 SP1 CR05 64bit on Apache Lounge v11 2.4.16 64bit on Windows 2012 R2 ? 64 Bit

     

    Cause:

     

    Apache Lounge v11 2.4.16 64bit running on Windows 2012 R2 needs some specific OS settings to run correctly. It needs tuning of the stack reserve space.


    Resolution:

     

    Do the following tasks:

     

    - Open the Visual Studio command-line window.
    - Run the following command:

     

    editbin /STACK:524288 httpd.exe

     

    - Verify that the stack reserve space has been updated to 80000(hex).

    Additional Information:

     

    To run editbin command, you need to have Visual Studio installed. The Visual Studio Express version includes it.

     

    The "Microsoft Visual C++ 2017 Redistributable (x64) - 14.10.25017" installs it here by default :

     

    c:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Tools\MSVC\14.10.25017\bin\HostX64\x64\editbin.exe
