@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 -

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

@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
-
This post is deleted! -
here it comes again, ~12 hours of inactivity, dead 5 minutes after the print finished ?!?!
-
@arhi what is the M122 please?
-
@JoergS5 I didn't do M122 I just rebooted it, turned on debugging on net, web and few others turned on logging on serial port and let it run so it catches log if it happens again as even dc42 did not find anything useful in the m122 last time so .. collecting debug data now
-
@arhi ok, hope you find something. Good luck!

I'm not turning the darn debug off till the darn thing dies again so we'll see .. -
not crashing while debugging turned on ...
interesting thing, no apps connecting to duet (rpi with duetlapse off, web browser closed all the tabs referencing it on all computers...) and I see this in the debug:

@arhi there is always a bit of network traffic like ICMP broadcasts. To analyze, you need wireshark or similar and your pc network card in promiscuous mode. But the switch might hinder traffic analysis.

yeah I have wireshark but the printer is on managed switch that does have bunch of fancy options but does not allow sniffing
and I don't have any hub's around any moreit's idle for ~20 hours now I'll try to print something later afternoon with debugging on, who knows maybe I reproduce the issue
-
managed switch and no mirror option?
if its on a pi tough you can run tcpdump over ssh and pipe it to wireshark
-

Yeah, I run few dlink "Smart Copper Gigabit Switch DGS‑1224T" and if they have the option to mirror I did not find it
(I had a need for this few times already). I had one 100mbps 4 port hub I used to use for analyzing traffic but it died last year and with this ^#$^%#$#@! hitting the planet I did not get new one yet..if its on a pi tough you can run tcpdump over ssh and pipe it to wireshark
yeah, no, its duet2 and I have not tried, yet, the duet2->sbc connection...
-
can't reproduce the darn thing, running debug for almost a week, giving it 24-70 hours break, everything works like expected ..
-
@arhi debug changes runtime behaviour, seems to be an error which is affected by debug unfortunately. Maybe there are other possibilities to analyze the error, debug turned off (like memory dumps). If you want to dig deep, SWD debugging would be possible. Duet 2 did not expose SWD, but there was a thread here how this could be done. Duet 3 has the pins exposed.
From your profile description I saw you know servers. In my job many years ago we had a server with memory leak, and we didn't find the solution. The "solution" was to reboot the server every night. This might be a "solution" for this problem also, if the cost-benefit to find the solution becomes too bad.

writing software for 30+ years
well aware of that ugly fact SWD debugging would be possible
not an option
my electronics table is on the other side of the room from the printer and time required for doing that does not exist; we are talking about debugging an issue that I cannot reproduce on-demand, I'd spend time better doing code review than debugging it
.. unfortunately, time does not allow much more than storing a console log and reporting results
