I sometimes have freezes on my Pi; what I intend to do is set up remote syslog or journal logging to another host, and see whether there's any clues in the last logs when it's gone down. There's also a netconsole kernel module that can be used to spray kernel log messages over UDP, that may be worth a look: https://www.kernel.org/doc/Documentation/networking/netconsole.txt > And nothing is in logs, too. It's possible it dies before the logging services have a chance to commit the logs to disk, hence my suggestions to fire it over the network instead. -- ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Jonathan Dowland ⢿⡄⠘⠷⠚⠋⠀ https://jmtd.net ⠈⠳⣄⠀⠀⠀⠀ Please do not CC me, I am subscribed to the list.
