Reboots/crashes - RRF ≤3.5.0-rc1
-
@dc42 Ok let's see, I've installed those last binaries and the "normal" 3.5.0rc1+ release on the 1LC.
After that I tried one of the jobs that failed earlier, and it completed without reversing the extruder (or crashing).
I'll try some of the other jobs that has failed too now and see of they also complete.
Should i still leave the "stuff" we put in daemon.g be there for a while btw?
(Copying this response to the other thread too, since it's refering to the same binaries)
-
@Exerqtor I don't think the stuff in daemon.g is relevant.
Are you able to take a Wireshark trace of your browser talking to the Duet? I have a theory that the "0.6<CR>" may be from the Accept-Language header that Chrome is sending

Okol, i'll remove the
G4
before the loop in daemon.g, and keep the rest.And I will try to look into the Wireshark trace. Have to read up on what it is first
But I do also think the issue is Chrome, the last 24 hours I have only had two instances of Orca Slicer with the "Device" tab open and it haven't crashed once. If i do the same thing with two chrome tabs open it would have.

I THINK, I've managed to do that trace now. But i can't see "0.6<CR>" in any of the data I managed to grab, or should i keep a trace going until it crashes and track it down?
Here is a HTTP trace from Chrome:

@Exerqtor sorry for chiming in once more...: I use Vivaldi here which is also Chromium-based, and I noticed that it works fine on my Desktop PC, but opened DWC tabs frequently crash on my notebook (either reloading endlessly or showing that "dead bird" symbol which is Vivaldi's replacement of the "Aw, snap" crash message of a Chromium tab) if the computer goes to some sleep or hibernation state (which the desktop PC does not do) and is resurrected later by moving the mouse or pressing a keyboard key.
With your finding here, I now see that as far as I can remember all the sudden crashes of my Duet which I blamed to "well, 3.5 is still in beta..." happened when the notebook was in use... don't know if that really means something though.
-
@NeoDue Interesting! Well if it turns out that it's something chrome/chromium sends that's causing the crashes i guess it might explain it
😅
@dc42 I let one chrome and one Orca Slicer tab open over night with the wireshark trace going (so we maybe could see which of them sends the "CR") .
And when I woke up today I saw that the machine had crashed at least once, so I checked the debug log and it turns out it crashed 4 times from 20:30 until I got up at 5:45.
I've stoped and saved the trace data, but haven't had time to through it yet.
Here is a fresh M122 at least:

@Exerqtor when I say <CR> I mean the control character carriage return. Wireshark displays it as \r so OrcaSlicer does indeed send that sequence at the end of the Accept-Language header.
Do you get any crashes if you connect Chrome to the Duet but not OrcaSlicer?

Oh there you go (this is out of my depth so sorry for the missunderstanding
😅
).Do you get any crashes if you connect Chrome to the Duet but not OrcaSlicer?
I'll give it a try later today, remove the IP adress from Orca Slicer entirely to rule it out.
Just out of curiosity, if this turns out being the reason for the crashing. Is it a Duet 3 Mini WiFi specific issue, or does it apply to Duet 2 WiFi / Duet 3 6HC WiFi as well?
-
@Exerqtor I have a 3 6HC here. Thus, if my assumption from yesterday is correct this applies to that board as well. But I guess it might be heavily dependent on how Chromium works on the corresponding computer, including anything that might be affecting this, such as e.g. how the computer handles standby states.
I will only be able to test my assumption in about a week since I am not at home, but I will follow this thread and try to recreate that issue both on my Duet 3 6HC as well as on my old Duet 2 then unless you already found a solution by then - you two are working really fast at the moment

The IP address is now removed from Orca Slicer, and I've got two DWC instances opened in chrome.
So lets play the waiting game and see what happens.

It's not Orca Slicer or "just" Orca Slicer thats causing the crashes, it happened again with it closed/not connected:

Doing the same with Orca Slicer now, no chrome connections and two Orca Slicer.

@Exerqtor may I ask about the computer you ran Chrome on in that test? Which OS? Notebook or Desktop? Screensaver, sleep or hibernation / energy saving mode enabled or disabled? Unless I overlook something, one of these things probably made the difference here.

@dc42
Hi david, I'm reading this thread as bystander. I asked myself if it is possible that the error occurs when the connection is interrupted but the socket is not closed and RRF is running in an timeout?Maybe I'm totally off, but as far as I know the RRF is opening an DMA channel to the WiFi/Network stack and the socket handling is done over there.
What will happen if a client is sending a partially delayed http header like
GET /rr_model?flags=d99fno HTTP/1.1\r\n Host: 192.168.10.x\r\n Connection: keep-alive\r\n X-Session-Key: 4102879531\r\n User-Agent: BBL-Slicer/v01.07.07.89 (dark) Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36 Edg/107.0.1418.52\r\n Accept: */*\r\n Referer: http://192.168.10.x/\r\n <VERY LONG DELAY> Accept-Encoding: gzip, deflate\r\n Accept-Language: nb,no;q=0.9,en;q=0.8,en-GB;q=0.7,en-US;q=0.6\r\n \r\n
The socket will stay open and later on run into an timeout, but the DMA channel is still open and partially written. The buffer gets freed (on stack), but the client or WiFi/Network stack keeps writing to that address via the opened DMA after the <very long delay>.
Maybe the idea is totally off, then just ignore it.
I was just thinking about another behaviour I observed when using DWC over an VPN tunnel, sometimes the RRF just stopped after I checked the status of the print and disconnected the VPN.
Edit:
- No timeout in the Network stack
- Timeout in the RRF
- Open DMA channel

It's on a desktop running windows 10 pro x64, hibernation/powersaving has been turned off since i'm running these tests.
So it's eiter chrome thats making the issues OR both. That we will see if it crashes with only Orca Slicer running (as it is now).
@dc42 So i just came home, and it's been no crashes since 05:50 this morning at least, this is with only Orca Slicer open. Gonna let it stay idle like this until tomorrow morning and see what happens. But i got a sneaking feeling Orca Slicer (by itself at least) ain't the cause of the crashes.
-
@Exerqtor have you ever seen this issue when running DuetWiFiServer 1.27? If you haven't, or you are not sure, please try it.
-
@dc42 Not sure, but i'm pretty sure it came after moving from 1.27. I'll revert to it now, shouldn't be an issue to run 1.27 with 3.5x on everything else?
-
@Exerqtor you can use 1.27 with 3.5x
-
Ok, with that it's now on WiFiServer 1.27, and i'm back to having two tabs with chrome and one Orca Slicer instance (since that seem to be what made it crash most often). #waitinggame

@T3P3Tony & @dc42 Just had a crash on WiFiServer 1. 27 as well:

@Exerqtor thanks! Let me add my observations in detail, maybe they do help someone here - I honestly don't know what happens in detail when the browser is open on a "sleeping" computer:
- Desktop PC running MX Linux or Linux Mint with Vivaldi open and no kind of powersaving except turning the monitor off active: dwc tabs do not crash, Duet does not crash.
- Notebook (in my case an old MacBook Air) running Windows 10 x64 with the same Vivaldi version active, hibernation turned off, but higher sleep modes active: tabs with DWC frequently do not recover if the computer is woken from sleep. Duet crashes occur (on a Duet 3 6HC running RRF 3.5.0 beta 4 or 3.5.0rc1), but not every time the browser tab crashes. Several browser tab crashes seem to increase the risk for the Duet itself crashing however, as far as I remember.
I still have my old printer here which runs on a Duet 2 Wifi with RRF 3.3 or an early 3.4 version. If it helps anyone, I could try to recreate those crashes in the new board and then check if the old one might be affected as well.
