Device: Pro12 CT9223W97
Having the same issue, receiving error code after a half hour or more of "1 job". Original data was transferred from the desktop to Pro12 main storage (14,000 epubs) Caibre proceeds to process the on-board library, then stops with error codes:

calibre, version 3.15.0
ERROR: Error: Error communicating with device



Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 87, in run

MemoryError

Deleted driveinfo.calibre, but no metadata.calibre found on the device. Rebooted both devices, and it seemed that there was a longer processing time before error.
Also, Calibre 3.15 has been shutting down by itself when ticking an action button, as well as when closing the error box.
