Serial Exception: device reports readiness to read but returned no data

[jericholab]

The pilot user reported several failures of the RDL-syncing script. The error happens both with the service and the manual execution in the terminal. The exact error is:
Traceback (most recent call last):
File "/home/orangepi/SHELF3/WIRED-logging-RDL-USB0.py", line 87, in
data = ser.readline().decode('ascii')
File "/usr/lib/python3/dist-packages/serial/serialposix.py", line 595, in read
raise SerialException(
serial.serialutil.SerialException: device reports readiness to read but returned no data (device disconnected or multiple access on port?)

The error happens about once a day.

It would be useful to be able to reproduce the error on the Montreal unit. I also wonder if the quantity of active sensors play a role. They are currently ALL active on Greenhouse. It would be possible active ALL on Montreal or deactivate some on Greenhouse.
