Thanks Sebastian, I was just wondering if it could be applied on its own as I have a site that can't currently be upgraded from an early 7 version due to a third party module conflict. I'm in the process of bringing all my sites up to 7.4 as I've been getting the max cpu issues for a while.

you may try backporting fixes in DNN Core yourself, but I would stay away from it and get your module fixed or replaced.

I encountered an identical situation,  for me it was confusing, as I tried everything,

1. I had my hosting company conduct a security audit on my dedicated server, nothing came out

2. Examined online traffic using various tools, nothing came out.

3. Created a clone copy of the installation, nothing came out.

4. Carried a comprehensive virus scan, nothing came out.

5. Examined the server events log, nothing came out.

6. Increased the RAM and Core, still did not help a bit .

I had someone examine the dump file live with full admin access, and in less than two hours was able to pin-point the troublesome method from a third party module.

I immediately had the vendor fix it.

From my experience the high CPU usage by the IIS worker process is mainly due to third party modules.

My host just put a limit of 250MB on my app pool and said I was using 650MB. Nothing has changed in months in the code except DNN upgrades. They couldnt tell me when this started.

of course the scheduler won't start and the site relies on that to do the eCom functions...

( I want to cry )
