If you only get four addresses in the backtrace, that's normally a WDT. Also in this case. The backtrace then only is the WDT abort. Also, as the watchdog normally does not trigger on the task causing the issue, this isn't easily debuggable. We could try to catch the WDT info that's currently only sent to USB, but even that is mostly no real hint. For example if something blocks event processing, the DukTape watchdog will eventually trigger with… E (139142) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time: E (139142) task_wdt: - OVMS DukTape (CPU 1) E (139142) task_wdt: Tasks currently running: E (139142) task_wdt: CPU 0: IDLE0 E (139142) task_wdt: CPU 1: IDLE1 E (139142) task_wdt: Aborting. abort() was called at PC 0x400e709c on core 0 So adding the MyEvents.m_current_callback info to the crash debug data would make more sense.

Which firmware are you using (the URL you download from).
Best approach is to use Michael’s a2l script, give it the backtrace addresses, and the .elf file for firmware, and it will output an annotated backtrace that we can see where the crash occurred.
Regards, Mark.

More info from crash. I see the following errors before crash (picture attached). Now i disable vfs logging, and run a can loggint to savyyCAN, this is the fastest mode to crash the module. i receive ~700k can messages.
