Explanation: GWCheck cannot read a specific record in a message database (msgnn.db).
Action: Perform a structural analyze/fix on the message database by supplying the name of the message database in the User/Resource field. See "Maintaining User/Resource and Message Databases" in "Databases" in the GroupWise 6.5 Administration Guide.
Action: If the message database cannot be repaired, manually restore it from backup. See "Restoring GroupWise Databases from Backup" in "Databases" in the GroupWise 6.5 Administration Guide.
