kthread starved for jiffies!

[blurb2m]

This is what I was able to snap a pic of prior to having to hard power down the server.

cu_sched kthread starved for 7163240 jiffies! g345411 c345410 f0x2 RCU_GP_WAIT_QS(3) 0>state=0x0
 

I'm VERY NEW to unRAID. Do I boot and run 'diagnostics'?

Here is my diagnostics file.

You're overloading your CPU. or at least that's how I've always interpreted it.

I've never seen % higher than 30 on the CPU. i7-4770. 

 

I need supervision when it comes to that then.

You might want to google for " cu_sched kthread starved for jiffies".   Apparently, it does happen occasionally with several different Linux Distributions over the past couple of years.  In my limited search, I didn't see anything that really looked like an answer.

Ditto

 

Same quick search basically pulled up no answers, except that the users who did have it upgraded to later kernel versions and it went away on its own.  

 

Try upgrading to 6.4

Ran the upgrade plugin to 6.4.0-rc7a. It hung prior to rebooting and I had to hard power down again. 

Tons was flying by during the hang that my phone couldn't even catch it on the home theater screen.
