Describe the bug
WeatherChimes project; System runs as expected for hours, to many days, then experiences periodic Hard Faults.

Example of Errors file output:
name | instance | Problem. | Corrupted | Failures | File_Source | Line_Number
Chime | 4. | Hard_Fault | 0 | 1 | SD.cpp | 360

Data continues to log to CSV file after Hard Faults
While SD data looks good, the system should not experience known hard faults before release to field operation.

Hardware in Use
Chime #4 (Chime #3 seems to be experiencing additional SDI-12 related hardware issues)
Feather M0 WiFi
Hypnos Board: SD, DS3231 RTC, 3v 5v Power rail switching
TSL2591
GS3 (SDI-12 soil moisture sensor by Meter)
SHT-30 Air Temp, Humidity

To Reproduce
Steps to reproduce the behavior:
Change WiFi router info in arduino_secrets for: SECRET_SSID, SECRET_PASS for your internet router
Ask Will or Chet for arduino secrets for MQTT broker and input
Upload attached WeatherChimesV4SDSleepMQTT.ino and config.h to WeatherChimes Hardware

Expected behavior
System should measure sensors, log to SD, and publish data to MongoDB via MQTT with no hard faults or hanging.

Fixed, Hypnos on Chime 4 is different version and CS pin assignment.

Nevermind,
WeatherChimes continues to hard fault as described in the original post. The system recovers with the reset and will operate a while before faulting again.
Logs to SD and MQTT are successful.
But on SD, data is distributed to a lot of files because a new file is created each time the system resets. New files are not a big deal, but we need to figure out the hardfault issue.
