This caused the page file to fill to its maximum file size and then DWM would crash as it ran out of resources. We have experienced this issue with Windows 10 but our issue was caused by a memory leak from Ivanti Application Control programme. In the assembly instruction at dwmcore!MilInstrumentationHandleFailure 5c530 in C:\Windows\System32\dwmcore.dll from Microsoft Corporation has caused an unknown exception (0xc00001ad) on thread 4 PVS using write cache 512MB non-persistantĭesktops : OS Windows 2016 with ServerVDI option(DesktopOS vda) 2 cpu and 4GB RAM I can't reproduce the issue at will but it tends to occur a few days after using the virtual desktop and most of the time when browsing the web.Ĭomponents: XenDesktop 7.15 cu2, PVS 7.15 CU3, VDA 7.15 CU2(Also tested with VDA 18.11) The only similar issue I saw online was a black screen during login. I was able to capture the dwm.exe dmp file but it didn't really give me too much information. Sometimes the desktop will recover but other times it will require a reboot. This issue occurs with multiple endpoints. When this occurs the screens go completely black or flicker black. Everything works great for a few days but after about a week the dwm.exe process crashes and calls out dwmcore.dll. I am in the process of testing Windows 2016 with the ServerVDI option.
