All of your Rivendell systems that share a database must be at the same
minor version level. For example, your servers are 2.10.3 ("10"), but if
you've upgraded the clients they are now at 2.11.0 ("11"). That difference
in minor versions means the structure of at least some of the tables in the
database has changed and requires the uplevel version of Rivendell.
Rivendell can convert from a lower database level ("242") to a higher one
("245"), and will do so the first time its processing routines get control
after an upgrade. So when someone logged on to your updated clients,
Rivendell automatically upgraded the database. Now, all your clients can
access Rivendell because they all "speak" database level 245, but your
servers can't because they're down-level.
You'll need to upgrade your servers to the same Rivendell release to get
things to work properly again.
