    Hello,

    Today I had my first BSOD for a long time.
    I have a freshly migrated windows 10 enterprise VM (few days old).
    Parallel Desktop 14 for Mac Pro Edition (Version 14.1.3 (45485) ).
    I have managed to do some basic memory dump analyses. Full memory dump analysis attached.

    BugCheck 3B, {c0000005, fffff803cfea7175, ffff8d8b9a4fe5f0, 0}
    Probably caused by : win32kbase.sys ( win32kbase!SURFACE::GetFirstLSurf+54 )

    STACK_TEXT:
    win32kbase!SURFACE::GetFirstLSurf+0x54
    win32kbase!DrvBackoutRedirectionDeviceBitmap+0x61
    win32kbase!DrvBackoutMDEV+0x54
    win32kbase!DrvChangeDisplaySettingsInternal+0x107d
    win32kbase!ApplyPathsModality+0xf6
    win32kbase!DrvSetDisplayConfig+0x760
    win32kbase!xxxUserSetDisplayConfig+0x2ae
    win32kbase!DrvProcessSetDisplayConfigParameters+0x7b
    win32kbase!DrvProcessDxgkDisplayCallout+0x1d0
    win32kbase!VideoPortCalloutThread+0x26b

    It seems the issue might be related to the Parallel Display Adapter since the STACK shows Video/Display calls.
    Or perhaps memory ran out?

    When the crash happened I had Skype for Business used for audio call plus screen sharing and few Microsoft Edge windows opened. Both apps are heavy memory consumer. The screen started to flick, went to back and only mouse cursor was seen, then back to normal (app windows reloaded) and this repeated before BSOD.

    I have 3GB memory and 2 vCPU assigned to the VM.
    Virtual memory was set to Initial size 1277MB and Maximum size 3000MB.

    Any thoughts or comments?

    Cheers!
