XR1000 Cpu usage high at idle

[PapaLung]

Hello again, I'm sure you are tired of my incessant whining, but, I've got another question concerning this router. What would cause the CPU's to be running at 80 to 90 percent while no devices are requiring bandwidth or little to no bandwidth? I have 1200 mps down and 42 up from my isp and router is a 2050V. The system information graph shows the same cpu usage as the one on the dashboard. Router was power cycled and no change, router is not hot and has ample power to it. I haven't factory reset it yet as it was done 2 days ago with a fresh firmware update/install. To be honest, if I have to factory reset this thing again, it's going in the garbage. Attached is a photo of the CPU usage graph.

Great to hear that, do let us know if the new router works as expected!

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

What CAT# lan cable do you have between the router and ISP modem? 

How many devices do you have conntected? 

Do you have QoS enabled or disabled? 

Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update?
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.

Has a factory reset and setup from scratch been performed since last FW update?

Pretty hard to say without knowing too much, looks like its fluctuating so quite possible some background processes occurring like downloading a cloud update (they're not big) or QoS is checking packets. If you're using Adblocker then that is more likely the cause. If you're not losing speeds and the router isn't hot then it's nothing to be concerned about.

As I stated above, modem is a nighthawk 2050v that I purchased, factory reset and firmware reinstall completed 2 days ago, 4 devices online at time of photo, only 3 using data per the network monitor data, an xbox series x sitting at dashboard, xbox one playing videos and my pc running duma os dashboard, nothing using over 200kbs up or down. QOS is enabled and I run that shutdown/startup process every time I reset the modem and router. I turned off add blocker, reset, and it's still showing the same cpu usage. Is it possible someone has hacked my router and us using or uploading/downloading information in the background?

[PapaLung]

So something I observed after I disabled adblocker is that in my logs, the date has reverted to Jan 24th (this has happened before) and it is creating a new log entry every 15 seconds or so. Is this normal, and if not, could it be the reason the router is using so much of the cpu?

[Netduma-Liam]

Can you provide an example of the log entry it's posting every ~15 seconds?

Does the date/time show correctly in System Information?

[PapaLung]

Here's a picture of the log this morning. The date is correct but the time is not. The date and time are correct in the system settings.

[PapaLung]

Also, since my last reboot which was last night before I turned in, I've apparently background uploaded 12+ million packets. Not sure if that matters or not, it's done this since day 1.

[PapaLung]

Restarted router and the Jan 24th logs came back right on que.

Is your modem a CM2050v? Just confirming correct model # info...

That is correct

[FURRYe38]

Does the top of the router feel extra warm or hotter when in this condition? 

[Netduma-Fraser]

Just to let you know I've passed this onto the team to take a look at, I haven't seen those log entries before so want to double check whether that's causing your issues.

[PapaLung]

Ok, thanks! I saved the log entries before my last factory reset a couple days ago and I also saved them again today in case they need them. There's some really wild sounding log entries in the full log they might want to see.

[Netduma-Fraser]

Please do attach them and I'll send them over!

[PapaLung]

Any suggestions on how I can get you these files?  I've tried attaching them to this message but cannot. 

[Netduma-Fraser]

You could use pastebin https://pastebin.com/index.php then send a link to it, you could password protect it if you like then PM it

[PapaLung]

Ok, thank you!!

[PapaLung]

I contacted the tier 2 techs this morning and they decided between the crazy log entries and the high cpu usage that they want me to try a new router. I appreciate everyone's help and knowledge on attempting to find a solution, it does mean a lot and I'm grateful people here are willing to share their knowledge (and put up with whining). I definitely have a lot more questions and am excited to learn, thanks again!!!!
