Anyone ?
-
@nagaculun sounds like the swap space might need to be enlarged
-
@sdetweil and how do I do that ?
Thanks
-
@nagaculun now now… google is your friend

@nagaculun Are you using MMM-GoogleTrafficMap? This module has a severe memory leak. Increasing swap memory will not help, as it just shifts the freeze to a later point in time. Other option is to setup a cron job that reboots regularly the RPi.
-
@Fozi i have a fixed GoogleMapsTraffic module on my github.
I submitted it, but it hasn’t been picked up… -
@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.
-
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>&1This 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. -
@Fozi said in rpi3 freezes every few days .. need help:
