The log excerpt is a little short but perhaps. I see in your log you have a 120 second archive period yet Belchertown took 125 seconds to run (which is 'very' slow), so it's possible your archive period is too fast for your hardware. What kind of pi are you on ? Something slower than a pi4 perhaps ?
If you are on slow hardware try disabling Belchertown temporarily and see if the problem goes away. Or alternately set your archive period to perhaps 180 seconds and try that. Or as always you might throw hardware at it and use a faster pi....but it looks like you're asking your hardware to do too much too often. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
