Something from Dayz is causing ucrtbase.dll to crash, forcing Dayzserver_x64.exe to stop working thus crashing the server.
This has been going on for a long period of time, with different provider/hardware, and with system reinstallment and V++ repairs.

Attaching zip with minidumps created each restart. By reading the ucrtbase.dll, code 7b3f8 is _invoke_watson which is basically just a crash handler, so the actual crash is elsewhere which should be found in the minidumps which only you can read properly.
