An error has occured when dereferencing a variable or variable with path during some kind of configuration expansion (/SHOW -e command, on-line verification etc.).

Configuration expansion will stop and the command executed will fail.
The exact CML path to the configuration node where the error occurs is printed at the beginning of the message (before the colon).
