web died after successful print

@arhi please tell what is in print_start.g and print_stop.g, the two macros are called in the gcode file.

@arhi my idea was that in the macro files is something interrupting the connection. Beside G29S1 and G0Z10 I see nothing strange, but there are two other macros again which you should check.
Does your internet router have log entries, did the router disconnect to the internet, change IP addresses, intruder detection, firmware update with router reboot, or such things which would disconnect your Duet?

note that this works for a while now, many prints finished ok, this is the third time this happened, both previous times the printer was idle for few days and after print web died (so after first print executed after long idle time) ... after reboot I made tens of prints without a problem... looks like the only problem is when printer is on and idle for 3+ days and then I start a print.
Does your internet router have log entries, did the router disconnect to the internet, change IP addresses, intruder detection, firmware update with router reboot, or such things which would disconnect your Duet?
Yes I have logs, no it did not ask for IP again so I assume network stack did not restart. The printer does not see internet it is assigned static IP from the dhcp server that puts it on the lan with no internet access. I don't trust my iot devices to see WAN, only LAN. Also, duet is not "connected" to the router, it is connected to the managed switch, that's connected to the managed switch that's connected to the router so reboot of the router would not be seen by the printer in any way.
If you run Duet in Access Point mode
it is duet2ETHERNET
the only devices in my house on wifi are phones and tablets and those are on a separate untrusted network and those devices have to connect to VPN to be able to see anything

it is duet2ETHERNET
ok, then no WiFi problem
The reason Spinning module was sometimes a problem with the SDCard.
One possibility is to set a higher debug level for analyzing.

@JoergS5 said in web died after successful print:
One possibility is to set a higher debug level for analyzing, but I have not done it yet, so I cannot help how to do it in detail. One can set debug levels for specific modules.
It's not a problem to add additional debug levels but the problem is that I can't reproduce this easily. last two times it happened I added debug + usb but could not reproduce the problem.
-
@arhi you could try a keep alive program (etc....)
(wrong thought Maybe the httpsessions were full (8 of 8 used) removed)
-
@arhi what is interesting is that the data cache hit count. Cache data hit count 4294967295 is exactly 32 bit unsigned, maybe reached an upper limit.
-
@JoergS5 said in web died after successful print:
@arhi you could try a keep alive program to check whether it is a disconnect problem after long inactivity.
It is not. The long inactivity was before the print, web opened ok and during the print there was activity and it stopped working immediately after the print finished. So no "timeout" to speak of.
You could check M122 before crash, maybe the httpsessions were full (8 of 8 used).
If I can reproduce the problem on demand it would make sense but I can't. All three times it happened the printer was not in use for 3-4 days.
Where do you see 8 out of 8 ?!?!
Responder states: HTTP(0) HTTP(0) HTTP(0) HTTP(0) FTP(0) Telnet(0), 0 sessions HTTP sessions: 0 of 8??
Do you use additional programs to access the Duet, like monitoring programs, which may use connections?
No program other than web accessed duet in the times the problem happened (normally I do but the rpi4 that host those programs is of-line these days so, no)

Please ignore, this was wrong.
One thing to check is wipe.g

I wonder if mDNS is playing a role. It was disabled on legacy Duets for similar reason.

@JoergS5 the wipe has nothing to do with it but here it is
if !move.axes[0].homed || !move.axes[1].homed echo "X and Y axes not homed, aborting the wipe" M99 if state.currentTool < 0 echo "No tool loaded, aborting the wipe" M99 if heat.heaters[tools[state.currentTool].heaters[0]].current < 200 echo "Extruder too cold, no point wiping, aborting the wipe" M99 ; Drop all motor currents down M400 M913 X30 Y30 Z25 M83 ; -135, -116, 115, 125, ; ,104....++++++++++++++++++++++.... ; ....++++++++++++++++++++++.... ; ....++++++++++++++++++++++.... ; ....++++++++++++++++++++++.... ; ,63 ..|.++++++++++++++++++++++.... ; ..|.++++++++++++++++++++++.... ; ..|.++++++++++++++++++++++.... ; ,30 ..|.++++++++++++++++++++++.... ; ....++++++++++++++++++++++.... ; ....++++++++++++++++++++++.... ; ....++++++++++++++++++++++.... ; ,-112....++++++++++++++++++++++.... ; .............................. ; .............................. ; ,-121..............................

But web itself is pinging it non stop (fetching the model json, displaying temperature etc etc)

dunno, I don't use mDNS as I had issues with it on windows so my router is configured to add entry to local dns to .local.lan or .local.wifi for all dhcp leases so I use ender5.local.lan to access it so local dns, not using mdns at all
- Disabled mdns in legacy Duets because of code quality issues causing reboots, https://forum.duet3d.com/topic/8352/duet-0-6-randomly-reboots/5
yeah but no reboot here, the duet runs ok, this time the web died after the print but usb/paneldue worked ok, last time web died in the middle of the print but print finished ok, paneldue was ok, I just could not connect using web.... I was running later on with debug on for few modules but could not reproduce the problem, today it happened again, the only similarity, the printer was idle for few days (not printing, but I did access it via web to check in some config details etc.. and basically the tab with dwc was open most of the time)

@arhi Error 10 Could be that you have a recursion somewhere.
Error 10 is an addition of 0x02 and 0x08 according to
https://duet3d.dozuki.com/Wiki/Error_codes_and_software_reset_codes -
@JoergS5 said in web died after successful print:

In that case, it would die much faster; but no, no recursion here. I do call same file from multiple places but never recursive

@JoergS5 said in web died after successful print:
@arhi but some overflow is the reset reason of your last reset. Maybe the cash overflow above, or another overflow. For overflow reasons, I only found the recursion as a cause, but maybe you're first for your overflow reason.
Well, the board did not reset! As I wrote, only the HTTP module or NET module died (did not restart, stayed dead), everything else continued to work ok as nothing happens, continued printing, parsing g-code...
-
@arhi The M122 reset reason is the reason of the reset 131 hours ago. The error 10 could be related to this access error.
-
@JoergS5 yup, that M122 happened before the ~130 hours of inactivity
