disappearing messages when disk is full

[mroda88]

@wesketchum noticed that sometimes when the logs are written on a disk that is full, messages simply stop being written, without any ERS Issues (or any kind of exception) being raised by the system.

It has been noticed that ERSIssues continue to flow to kafka when this happens. So the problem is not super urgent, but this can clearly impact the possibility of navigating the history of the system.
