Severe CPU

Noticed nothing was working just now, and logged in to find a warning about hub CPU and my zigbee netork was offline


As i run all automation on Node Red, and just use hubitat to pair devices which is, i guess, minimal compared to some folks, i cant see what would cause such a high cpu load.
Clicking on the links in the error message to go to device stats, resloves to a 404 error page!

Ive looked through logs, but can really see what could be the culprit
Any suggestions
Cheers

Maybe start by telling us what hub firmware you are on? There were some changes in recent updates that I believe were supposed to help this.

Is this a C5, C7?

Do you have Zigbee, Zwave, LAN devices, cloud integrations?

The link in that message is supposed to take you to the app stats or device stats page. When you were in logs, did you tab over and take a look at those stats? It could be a device and not an app causing this.

Yes, clicking the links in the alert message lead to a 404. I reported this same thing about 3 days ago. Mine was with a db size warning.

Wonder if @gopher.ny is aware of the 404...

Mine is a C4
Firmware 2.2.9.145

The links don't work, as mentioned I hit a 404 error page

As the zigbee network was down, i needed to restart the hub.
The hub hung during restart and did not recover. Only way to bring it back to life was unplugging power, and plugging back in

Before trying to restart, i took this grab from the devices page


It seems high, but ive never looked at it in the past, so couldnt know either way.
I have had this device running without change for 12mths odd and no cpu issues until now

Not considering the hub had been up ~2 trillion ms - busiest device is using 0.1% of the hub’s available time.

Are you running any apps that do a lot of HTTP calls (generally cloud interfaces)?

This will be fixed in the next release. Please go to directly to http://your.hubs.ip.address/alerts in the meantime.
