null pointer exception on RPi 0W "Oops - undefined instruction: 0 [#2] ARM" #6251

Open xsolinsx opened 2 months ago

xsolinsx commented 2 months ago

Describe the bug

getting this when trying to upload a tar.xz file using a telegram bot written in python https://github.com/xsolinsx/RPiCamBot/blob/master/WebcamBot/utils.py#L89 it backups the folder of the telegram bot + some additional files specified in the configuration this archive is then sent to my telegram user from my bot, this is the step where it gets stuck, last time it broke at this situation

I am sending the automatic backup.[███████████████░░░░░] 78.38%
18.00 MB/22.96 MB
1.12 MB/s 16s/20s

the tmux window then is blocked on the logs reported below and I cannot kill the python process in any way

Steps to reproduce the behaviour

it does not happen consistently, but I experienced this multiple times in the last months, every week or so I don't have a clue of what the steps to reproduce could be I would say get a telegram bot api key, install the required libraries and try to upload a file of some MB, but I'm not sure this would definitely cause the issue to occur these lines should be enough to create the client with the library I'm using https://github.com/xsolinsx/RPiCamBot/blob/master/WebcamBot/timelapse_bot.py#L25-L36 while these lines should be enough to actually send a document https://github.com/xsolinsx/RPiCamBot/blob/master/WebcamBot/utils.py#L98-L104 (the progress function could be useful to debug but it's not mandatory)

Can you try adding over_voltage=2 to config.txt and see if that helps?
