Duet3 + Pi DWC freezing

[mwwhited]

I am seeing this issue as well after updating to RC12. Here is my config.g I wasn't printing or anything at the time that my RPi froze. It was just idle for the entire day. I will leave it running with the console logging and see if I can catch any errors if it freezes again today.

I think I have found the issue but I am still testing the fix. I am now printing layer 55 of Carlo's test file and no freeze so far.

[jay_s_uk]

@chrishamm was this linked to my issue by any chance?

[chrishamm]

@jay_s_uk Yes, I think so. We'll provide a fix shortly.

[mwwhited]

The website is still responding and the SBC/RPi seems that's it's still running but I did get this message

[mwwhited]

After the above message the daemon.g did not running. I was able to recover it by hitting emergency stop. I didn't get the total lockup like I did yesterday where the UI stopped responding as well as I was not able to SSH into the RPi... but this time is different as I cam logging the messages to the console as you suggested above. I'm going to allow it to continue running overnight to see if it freezes entirely.

[jay_s_uk]

@mwwhited

Thats the same message I was seeing. https://forum.duet3d.com/topic/16240/print-frozen-rrf3-01-rc12-and-dsf-2-2-0/12
When I got that, the system would lock up, the GUI would become unresponsive but I was still able to SSH into the pi.
Just to let you know that you're not alone.

[Carlo]

@jay_s_uk

Were you able to reload the screen to get control back ?

[jay_s_uk]

@Carlo

I could reload it but none of the buttons did anything.
Seems to be something locking the daemon file up and killing the pi side of things.

[Carlo]

@jay_s_uk
Yeah if I reloaded it worked as normal until cal or uploading gcode and the circle continued.

[Carlo]

Hi,
Connected to pi via desktop Chrome browser/and Pi screen
Still having this issue after update to 3.1.0 via apt-get
Also now get this error and constant network drops?
5/16/2020, 3:10:10 PM Failed to get file list (don't get this error on the Pi only over network)
Target drive is unmounted

No files show in system via web browser but are there on Pi screen
And still freezes after G32 or uploading gcode files may be more this is as far as I have gone on both Pi and web browser.

Cheers
C

[chrishamm]

@Carlo Can you confirm that you are on RRF 3.1.0? I haven't been able to reproduce it since that version. If it happens again, please run M122 from a serial monitor connected to the Duet 3, M122 "DSF" via the web interface, and post the outputs here.

The outputs of sudo ls -lR /opt/dsf/sd and sudo journalctl -u duetcontrolserver -e may be interesting, too (executed from a Linux terminal).

Hi Chris,

I have just installed a new image of duetpi and its the same issue file name 2020-05-15-DuetPi.img.

@Carlo Thanks, that's all looking good. I am a bit puzzled why DWC shows the first volume as not mounted. May you share the output of http://duet3/machine/status too? In most browsers, you can switch to raw view somewhere at the top, which makes copy&paste easier.

Please post those outputs only after a freeze has occurred and before a (firmware) reset.

@chrishamm

Hope this right

@chrishamm said in Duet3 + Pi DWC freezing:

Please post those outputs only after a freeze has occurred and before a (firmware) reset.

Sorry Chris I'm not sure I made this clear it freezes every time also sometimes when it echoes to the console DWC loses connection and needs me to reload the page not restart the system also I have reinstalled a number of times with the DuetPi image on brand new Sandisk Ultra SD cards always the same problem.
Just want to make sure I have given you as clear an understanding of the issue I'm having as my failing faculties possible can.

Cheers

@Carlo

To rule the Pi out I swapped out the Pi4 for Pi 3B+ but has made no difference exactly the same ?
Thought it may help.
