The mismatch could lead to corruption of the configuration database.

- **Severity**: error
- **Cause**: The schema is incompatible with the installed Junos OS.An internal software failure occurred.
- **Action**: None; mgd will rebuild the schema based on the current Junos version.Contact your technical support representative.
