## Symptoms

- Policy installation on a VSX Cluster fails with this error in SmartConsole:

`"/opt/.../conf/<Policy_Name>.pf", line <X>: ERROR: Duplicate keys <IP Address in Hex format> in table 'cluster_members_ids_by_ips'`

## Cause

Data inconsistency in the configuration of the VSX cluster interfaces on the Management Server.

For example, the Network Mask of the Management interface was changed. As a result a Virtual System object in the database contains 2 interfaces with the same IP address and official name:

* ifndex 2 - :officialname (Management)
* ifndex 3 - :officialname (Management)
