RT-AX88U - CPU 100% - top useless

[RyanFromIT]

My CPU keeps going to 100%. Some times all 4 cores

Running version : 386.1_2

Skynet isn’t installed. I opened the installer and quit.

first check, CPU 100% on all cores. And top at that time.


Second check and top at the time


It’s intermittent and lasts about 5-10mins. And not during the times the spdMerlin is running.

Any help is greatly appreciated.

It's doing I/O, so the first thing I would look at is the USB disk and anything that uses it.

It'll be uiDivStats. Your USB write must be quite slow. Try cache mode

How do I check what processes are using the disk? iotop doesn’t exist on the router.

So far with Diversion disabled, it seems to be normal usage now.

@Jack Yaz
How would I change the settings in uiDivStats? Looks like I can only change 2 settings:

Thank you,

Cache mode is already enabled (tmp or none display)
You can use atop which will show DSK usage, but I'm not sure it breaks it down per process

opkg install atop

c then enter.

 

[RyanFromIT]

c then enter.

That changes it to none. That doesn’t seem right to me.

c then enter.

So,

I change the c option to none. Enabled Diversion. It’s been doing it intermittently again. This is just now (30mins after doing said steps)



io only shows ~50%
