Anytime a new Adobe DRM client is released, an ECI device record is added.
How large are ECI files?
They are typically less than 1 Kilobyte per device record.
What happens if the server is missing an ECI device record?
That particular class of clients will not be able to individualize against the On Premises Individualization Server and errors will be logged to the log files.
What happens if a server’s CRLs are expired?
The server will stop functioning correctly and errors will be logged to the log files.
