RT-AC5300 System Load

[bloop16]

Hi,

I'm using a Asus RT-AC5300 with AusWRT 386.12_4.
After 2,5 days of running the Routers System Load suddenly goes up from nearly nothing to about 50%.

I get all the Data over NodeExporter/Prometheus/Grafana (Instructions NodeExporter)

On the Router there are following Addons running:

• amtm
• Diversion
• Skynet
• connmon
• scMerlin
• uiDivStats

and mounted over an USB-Stick
There is a noter Harddrive for CIFS Backups connected to the Router. As you see all Backups start at 02:00 PM without any problems for the Router.
The "overload" starts at a time when nobody is at home and there are no specialized Prozesses running.
How can i check the prozess which needs so much CPU load and whats the reason for it?

Thanks for helping!

Run top on the router to see which process is consuming the CPU.

Here is the Systemlog from the time when CPU load is rising

Diversion is known to conflict with dcd. Disable Diversion.

Think i have found the Problem in Post https://www.snbforums.com/threads/a...ert-process-and-free-memory.83014/post-844142.
Now have to wait for the next view days, and see what happens...
Then ill try Diversion!

Thanks for helping!

TrendMicro Data Collection Daemon is crashing even in stock Asuswrt. Disable TrendMicro bloatware and your router will start working much better.

You are running Node on an embedded Linux device...

Sooner or later, you'll run off the rails on the memory situation...

Already running since more then a year and never had problems with the memory.

Found the problem in AiProtection.
Deactivating the service makes cpu working normally again.
