I can confirm I have this bug as well but the Cayenne team has not yet confirmed it so it’s not being worked on. Unfortunately there isn’t an estimate on when they will get to it yet, just hang in there. Here is a workaround for the growing log the last time this bug was around: Bug Filed on 12-21-2015: SD become full in few hours - #8 by adam unfortunately the ram issue will need a reboot.
