Hi.
How are you powering your board?
Does this happen frequently with that project?
Regards,
Sara

power up using 150Ah battery, for at least 5 years of unattended installation. the unit is supposed to wake up twice daily and upload field data.
at least 1 crash after 15 days or so.

Hi.
It is probably some issue with the code.

Can you share you code? Please use pastebin, github, a link to google drive or dropbox, for example, to share your code.
