Looks like a stack overflow in Housekeeping. Can you see if increasing the 4096 -> 6144 in ovms_housekeeping.cpp xTaskCreatePinnedToCore solves this? In general, it seems best to arrange to marshal command execution, timers, events, etc, into one task (with a suitably large stack) and dispatch from there. Housekeeping issues that system.startup event, but also timer.1, etc. I’ll have a look at this. Regards, Mark.

The following script reliably puts the ovms into a boot loop:
vfs mkdir /store/events vfs mkdir /store/events/system.start vfs rm /store/events/system.start/startmeup vfs append "log level debug" /store/events/system.start/startmeup vfs append "server v2 start" /store/events/system.start/startmeup
Press the reset button and it loops with the log below.
It can be fixed by "make erase_flash flash" but this obviously erases your config.
If you swap the order of the two commands in the script, or if the script only contains on or other of the commands then it doesn't boot loop.
