Error: mainworker seems to have ended or hung unexpectedly

[Robert28]

Hi all,

since the latest beta release Domoticz crashes:

Code: Select all

Anyone already a starting point where to look?

Domoticz: V2024.7 (build 16268)
Platform is Fedora 40 x86_64

BR,
Robert

Revert back to previous beta.....

And check in GitHub what the latest changes are and if they could have impact on your environment.

[Robert28]

Hmmm... I did... no solution, also the latest August release crashes...Obviously related to a system update...

[waltervl]

Or power supply issue, or sd card issue.

[Robert28]

Domoticz is not running at a Raspberry Pi, but on a x86_64 system, so no SD card (HDD Smart is ok).

[waltervl]

Perhaps run Domoticz in a docker container. x86_64 is built on an Ubuntu environment ubuntu-latest (currently ubuntu-24.04) so there could be some mismatch with Fedora

[Robert28]

Hmm, I not a big fan of containers...

At this moment I suspecting the rtl_433 receivers, I have two of those one for 433 MHz and one for 868 MHz, especially the 868 gives time outs, changing the receivers does also change these time outs... (so not hardware related)... no clue..

[Robert28]

Another step, it seems to occur after Domoticz get's (for some reason) no information from rtl_433, resets the device and than 5 minutes later the watchdog is triggered:

Code: Select all

2024-10-14 03:45:04.578  Error: Rx433MHz hardware (28) nothing received for more than 1 Hour!....

2024-10-14 10:20:11.526  Error: Failed to start gdb, will use backtrace() for printing stack frame

(Note: I have a script running that detect that Domoticz has crashed and restarts Domoticz automatically).

Anyone a suggestion?
