Onion Omega 2S+ File System Corruption
Recently we have been noticing file system corruptions on multiple Onion Omega 2S+ devices. We are running a custom software on the system (using Golang) that reads from a set of sensors and sends the data over MQTT using a 3G cellular module. The data is also stored on the SD card attached to the board.
We are observing the creation of a lot of (up to 6000) 0 byte files in the root folder. The system suddenly stops and we cannot log in to the device using WinSCP/Windows Powershell or any SSH client. If we do a power cycle at this point, the device gets bricked. We know how to recover a bricked device, using the web recovery mode but we want to figure out how to stop these file corruptions from happening. Any help is appreciated.
Have you tried switching the SD card or is this happening on (what seems like) numerous devices?

@mfahsan There was a similar issue reported by a user and investigated by Onion and the root cause was determined to be interference from the cellular module. As I recall the resolution was shielding of the SOC, search the forum for "corrupt" in the last 18 months .
