Hello all, I am seeing a 100% CPU Usage on my gateway and I am not sure what is causing it. How can I figure out the issue? Status Overview: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/a/8a9ee7d71c04844341edb0b97f191e087ce8ef5c.png) Threads: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/9/e9b8c8724763cc532a1b4561bd64c9f6897c158a.png) In the logs, I see repeated info logs from client session which have the message "WebSocket disconnected from sessions" and I have many warning messages from client session with the message "Received event for missing view". I do have the views so I am not sure why it says missing view. thanks in advance ---

You'll have to provide us with a bit more detail for anyone to know where to point you to start looking. Provide specifications on your gateway server (RAM, CPU cores, vm/baremetal, sharing a VM with a db, etc), as well as the number of connected devices and normal amount of perspective sessions you have connected. If you have a large amount of trending in perspective that can put a large load on your gateway. Also, if you haven't already, check out the [sizing guide](https://inductiveautomation.com/resources/article/ignition-server-sizing-and-architecture-guide) from IA. You may just be running an undersized server for your workload. ---

"Light duty" would be single page Perspective apps running in Workstation, or Mobile, or single-tab browser sessions, displaying dashboards with real-time tags, up to an hour (-ish) of real-time trends, and pre-computed statistics for longer time… ---

I agree that calling support is your best course of action. I will add that I've seen cameras drive up CPU utilization if your camera settings are aggressively streaming frames to an HMI client. If you're using a camera, try temporarily removing that and see where you're at. If it is the camera you can adjust the configuration to cut CPU utilization.
