Hello,
Since last Tuesday, I've been getting a lot of cpu spikes on my terminal server. I've looked up and tried just about everything I can find, and I can't figure out what is causing it. I've ran both kernrate and xperf and even after viewing the results in windows performance analyzer, all I can tell is that it's related to ntoskrnl.exe. Every time I drill down into the ntoskrnl all I see is more ntoskrnl and can never find a driver or anything else that could be causing the issue.
Some back story on this is that it's a VM that I recently migrated off of HyperV over to Scale Computing HC3 Hyperconverged SAN. I migrated it over last weekend, and last Monday it was working perfectly fine. halfway through Tuesday is when I started noticing spikes. It only does it after people start remoting in to it. After hours when no one is on it, everything is fine. I do have the xperf .etl file if anyone would want to see it.
