Just grepping through the nohup.out log file I don't see failures of any kind. Nor in the system log file that was posted. It is interesting the data found in the nohup.out though. Not for failure, but for what is recorded.

There is no rain in the 60 min total ever noted. However, this is found in the last two entries:
grep -n currentTotalRain nohup.out | grep -v '0.0'
67987:currentTotalRain  =  0.1397
68096:currentTotalRain  =  0.1397
During the last two entries there must be rain falling, but the interval between rain measurements has not reached 60 minutes.

There are voltageValue variable values equal to as low a 3.32 and several times the voltageValue variable under 4. Every other time it is above 4.
grep -n voltage ./nohup.out | grep -v '4.'
3118:(' voltageValue = ', query=INSERT INTO Sunlight(TimeStamp, Visible, IR, UV, UVIndex) VALUES(UTC_TIMESTAMP(), 0, 0, 0, 0.000)
7102:(' voltageValue = ', 3.692625)
8803:(' voltageValue = ', 3.3195)
8937:(' voltageValue = ', 3.3223125)
9915:(' voltageValue = 'trying database
19356:(' voltageValue = ', 3.706875)
20999:' voltageValue = ' before query
25682:(' voltageValue = ', 3.6898125)
32078:' voltageValue = 'before query
33762:(' voltageValue = ', 3.6916875)
37721:(' voltageValue = 'before query
58788:(' voltageValue = ', 3.687375)
60579:(' voltageValue = ', 3.7085625)

Every time, except the last two entries for this variable, currentAS3935Interrupt is equal to 0. 

grep currentAs3935Interrupt nohup.out | grep -v 0
currentAs3935Interrupt =  4
currentAs3935Interrupt =  4
That is from the Lightning detector so matches up with the current rain variable.

I'm going to research and see if there is software available that tests more circuitry and memory in a pi. I've had mysterious crashes on workstations where the only theory I ever came up with was a stray gamma ray flipping a bit. However, when pi's seem to randomly start crashing, I think there is likely something going that is real failure mode but unpredictable. It would be nice to have a routine that would load the pi up in different test modes to predict where failures occur. Dell had a test routine for their workstations that put each component through a procedure that many times would identify a problem. And, the good ole memory test routine helped me out in the past. I just don't know yet if that exists for the raspberry pi.
