I'm going to have to leave this to Matthew I'm afraid. You definitely appear to have a communication issue with the weather station (READ failure) which occurs at 03:58 approximately, and there are several restarts of weewx which are automatically attempted by weewx. As to the cause of the initial read failure and as to whether or not weewx and the driver have taken the correct expected actions as a result I am afraid Matthew's knowledge is required. Looks somewhat similar to the classic fousb lockup issue where the usb just refuses to communicate and the only way out is a station reset in that instance. Maybe an automatic reboot will be the only way out of your particular problem - but only Matthew can say!!
