rpi3 freezes every few days .. need help

Fozi

@sdetweil thanks for the heads up!
Didn’t know you fixed it. I’ll give it a try for my next MM version, I’m currenttly planning.

@Fozi I dont have the MMM-GoogleTrafficMap. Even just the default clock module has the issue.

I setup a cron to reboot every day at 6am; and it happens as well.

@sdetweil

Just modify accordingly. Now wait and see. Thanks.

@sdetweil
It still freezes even I made the modification.

@nagaculun bummer…

@nagaculun Are you sure that the crontab is really executed? ssh into the RPI, execute ‘htop’ and check the uptime. The uptime should be the difference between the cronjob execution and the actual time.

For setting up the crontab, that reboots the RPi I needed priviledged rights.

$ sudo crontab -e
 and then insert, e.g.

15 1,9,17 * * * sudo shutdown -r now >/dev/null 2>&1

This reboots the RPi at 01:15, 9:15 and 17:15 every day (every 8 hrs.).
Note the two ‘sudo’ for editing the crontab and initiating the shutdown.

Some experiences I made:

My “productive” MM runs on a RPi 3B+. I have also a normal RPi 3B, which I use as a test bench in the exact same configuration as my MM (I’ve use a cloned SD card).
Surprisingly, the 3B’s memory is not filling up and stalling like my 3B+.
God knows why.

Yes, as I literally wait and see when it happens.
