## SYSLOG Details
- **Message**: Schema sequence number mismatch
- **Help**: Process could not open schema because of sequence number mismatch
- **Description**: The Junos user interface schema file records all CLI commands and configuration statements available in the Junos OS. The management process (mgd) rebuilds the schema as necessary to be compatible with the Junos OS installed on the routing platform. A sequence number in the schema acts as a checksum that represents its content and format. A Junos process attempted to access the schema but determined that the schema's sequence number means that it is incompatible with the process.
- **Type**: Error: An error occurred
- **Severity**: alert
- **Cause**: An internal software failure occurred.
- **Action**: Contact your technical support representative. For more information, see http://kb.juniper.net/InfoCenter/index?page=content&id=KB19126.
- **Attributes**: -
- **Facility**: ANY
