          @nagaculun sounds like the swap space might need to be enlarged

                @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.

                    @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.
