DCS Crash with 3.01-R10 / DWC 2.1.5 / DSF 2.1.1
-
Back down at RC9 but my CPU fan is still not working correctly - really don't want to go back to RC7 but can't handle the constant noise.
I KNOW this fan can work correctly - has done so since RC1 .... why can't I see fan 2 on the dashboard ? (doesn't even appear in the display filter)
Has something changed in gcode ????

More hassle than I'm in the mood for
you could probably ssh in, stop DuetControlServer service and run it in the foreground to try and capture any relevant debugging info. installing and using screen would pervent DCS from being terminated if the ssh session is terminated.
sudo apt install -y screenand then runsudo systemctl stop duetcontrolserverfollowed bysudo screen /opt/dsf/bin/DuetControlServer -l debug -
At the time you couldn't ssh - the RPi wasn't responsive at all, if you had an SSH session open it just stopped responding.
I will try the screen though - what does that offer? - a non DWC web gui ?

Spoke too soon.
if you've got access to console/ssh could you also run something like top and see if it spots something to suggest DCS get stuck in a loop?

its a terminal multiplexer / window manager or sometihng like so. it achieves that dcs will keep running if you have a network glitch. if you run dcs in the foreground and ssh stops all the processes in that shell are terminated - with screen they can keep running.

First message

and then [screen is terminating]

I was getting those when I very first setup my D3 & Pi. Firmly re-seating the ribbon cable on both ends cleared them up.

Terminal dies as soon as the web connection does.
I'll try and run DCS through the session and see what it spits out. It'll be later on though as I'm on bedtime duty now. -
the only thing I could think of that with respect to DCS to complaining about the RDY pin is basically an interrupt storm which can grind the Pi to a halt. not sure if relevant though.

Well this sucks - it's just done the same thing with RC9 ..... I had screen running at the time and it reported nothing ....

I'd like to help the team figure this out but I haven't a clue where to start and I need the printer at least 'functional' even if there are known issues. Right now it isn't even functional.
I'm using a 4 Gig RPi 4 if it is worth anything (yes I know its OTT) ...

unfortunate, but still probably still helpfull for chrishamm. what happened to the ssh session timed out after a while or was it terminated immediately?

Terminated immediately ...

It's not a network glitch. When it happens it tends to take out the entire Pi. Completely. So using screen isn't going to help. I've managed to get the network to stay up about 3 or 4 times out of 40 or so crashes, in which case screen isn't needed as you can still issue commands.... everything just takes an age to respond. But yeh, as soon as the SSH connection goes a power cycle is the only fix.

That sucks. It's only been RC10 that I've had this issue on. To the extent that the first time it happened I went and checked to see if my router had died.

t
hats interesting; it means the cpu is able to relatively cleanly terminate the session as opposed to just freezing; although it doesn't help you.see below for correction. -
I wonder if something didn't uninstall or get overwritten in the 'downgrade' process. I never used RC9, I came straight from RC6

mostly a precaution to avoid terminating the process if the session is interrupted for other reasons.
-
@bearer I should say that there is no disconnect - just zero repsonse - no messages, it just stops ... I use a commercial tool (Secure CRT 8.7) and it still thinks it is connected but hitting enter just causes an on screen line feed.

ah, that is more what i was expecting. it would terminate after 30-60 seconds or so as a timeout; in turn meaning the pi forze or was too busy to close the connection. still good info one way or the other.

Yup it does ...

(i wonder if setting process affinity could isolate the hanging to leave a core running ssh etc, if possible in raspbian - anyways thats it for me today)
