## Symptoms

- During "fetch topology" from a ClusterXL, the following error is received:  
`
"Failed to save object XXXXXXXXXXXX. `  
`

Server error is: Validation error in field 'interfaces' of element #5 at object 'XXXXXXXXXXXX' @ 'Network Objects' --> Validation error in field 'security' --> Validation error in field 'netaccess' --> Validation error in field 'Specific network behind this internal interface' --> The referenced object 'XXXXXXXXXXXX_bond0.78-1' from table 'network_objects' does not exist in the database. (Code: 0x800415B1, Object contain invalid reference)`  
` 

Please contact technical support."`

## Cause

Interface and routing configuration are not correct and there is inconsistency between cluster members.  

For example, one of the cluster members has different subnet mask than other and that caused issue with GET topology function.
