Andy, you might want to work on your google-fu a bit more. This has been discussed 'many' times in the past, so it's searchable in the group archives. "database is locked" happens all the time on a pi, generally when you run too complicated a weewx skin (or set of skins or extensions) and they don't process fast enough on the limited pi resources. The file is indeed locked and in use when weewx needs to update it. You need to lighten the load on the pi: - do less - run less skins, run less extensions, set your WF to power-save to not do rapid_wind every 3 seconds - do easier things - run less compute/disk intensive skins (don't run weather34 or Belchertown or Belchertown+MQTT) - do it faster - reconfigure to use a SSD disk, not a SD disk (requires pi3 or pi3b+ and a better power supply) - or get a better computer than a pi if you want to do a lot of stuff Regarding the WF gear specifically, I found the weatherflow UDP driver 'very' stable running just vanilla weewx on something as weak as a pi-zero. I've had it running similarly on pi3 for almost 3 months now, so your problem is you are almost certainly trying to do too much on the wimpy pi platform. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
