Weewx hangs itself regularly with this error related to the WXT5x0 driver. It is always the rain calculation which leads to this error with some certain past weather conditions

Python3 version 3.8.10 running in this host.

Some times the rain measurement passes OK according to the log file;

This still happens, with Python 3.10.12

@matthewwall Do you have a clue why this happens?

Happy new year!
