  • Web Application crashes randomly IIS 10 - Windows Server 2019

    Apr 14, 2020 02:47 AM|juliocarreirasilva|LINK


    We have a web application on IIS 10, it crashes several times a day no pattern of time or related user request (sometimes there is no crash at all, also crash during the night when noboday use it),

    The server version is Windows Server 2019.

    I already installed a debug diag but so far was not conclusive.

    I really appreciate if someone give me a direction to investigate and identify the root cause.

    Best regards,

    you could use DebugDiag to analyze the dump file. Just choose “CrashHangAnalysis.”

    you could refer this link for more detailed steps:
