why dotnet.exe is terminated under IIS

Introduction
I do have WebApi on.Net Core 1.1 & simple test application executing some scenario with calls to my API in multiple threads. Web API is hosted under IIS on WS 2012 R2.
Problem
When I do start my test application with 20 threads in 20-30s test application begin to receive 401 error from the server. After some investigation, I've noticed that dotnet.exe process is suddenly terminated & restarted on the server on high load.
There is no information neither in my logs nor in Windows event log (only one from IIS AspNetCore Module about starting new process: Application 'MACHINE/WEBROOT/APPHOST/DEFAULT WEB SITE' started process '10248' successfully and is listening on port '23570')
I've tried to reproduce this on my machine without any success - this does not happen when my API is hosted in IIS Express from VS.
Question
What may be the reason?

My application is a GIS application:

Coldfusion10 + Apache web server

I am running an install of Coldfusion10 on my local Windows7 machine. I now want to configure it to serve the site on apache web server (primarily I want to use the apache mod_rewrite functionality to rewrite urls).
However, once I have configured Coldfusion to use Apache (via the web server configuration tool) my apache service is stopped and I cannot restart it.
On restarting I get this error:
Syntax error on line 2 of C:/apache/apache2/conf/mod_jk.conf:
cannot load C:/coldfusion10/config/wsconfig/1/mod_jk.so into server: The specified procedure could not be found.
I have tried re-downloading the mod_jk.so file that should work with my version of apache, and whilst that stops the above error being shown, me apache server still doesn start.
Anyone experienced this or have any suggestions?
Cheers
