Error while Running Linuxcnc

I am using Mesa 7i92+7i76+7i84.

Machine is under software set up stage, wiring completed.

I encountered the attached error in photo. The system runs ok, but it is 4 or 5th occasion the error occured.

What is happening wrong? Is it softw

The original error is a watchdog bite.
This means you have a latency issue
(or the watchdog timeout is set way too fast)

I would do a ping test:

ping -c 4 [card_ip_address]
sudo ping -c 30000 -i .001 -q [card_ip_address]

Where [card_ip_address] is the IP address of the 7I92 card
(probably 10.10.10.10 or 192.168.1.121)

The last command will take 30 seconds to complete

the terminal emulator results are as follows:

Latency test value screen shot attached, ran with 10 GLXgear and one 4k movie for 2 hour.

As I am noway an expert of these parameters, are they ok?

And one thing I noticed, the monitor goes blank sometimes for a moment, probably power issue. Now can such momentary power issue to CPU and MESA card create problem? Or could there be any issue with software download (and installation) as I had such issue before.

















 

The latency and ping tests look fine.

Momentary power loss could definitely cause loss of communications/latency

Also I am assuming you are running a 1 ms (1000000 ns)
servo thread, as a too fast servo  thread might also cause these symptoms
 

Watch dog timer is 5ms, HAL file attached.

Does that require any change?

What is the servo thread period?
