Cause

Database inconsistency.
Resolution

Create a backup of the psa database:


# mysqldump -uadmin -p`cat /etc/psa/.psa.shadow` psa  > /root/psa.sql

Check if the IP_Addresses table has record(s) with an IP address that does not exist in the ip_pool tables:


    mysql> select * from ip_pool where ip_address_id not in (select id from IP_Addresses);
    +----+---------------+--------+
    | id | ip_address_id | type   |
    +----+---------------+--------+
    |  1 |             2 | shared |
    +----+---------------+--------+
    1 row in set (0.00 sec)



    mysql> select * from IP_Addresses where id =2;
    Empty set (0.00 sec)



    mysql> select id, serviceNodeId, ip_address from IP_Addresses;
    +----+---------------+--------------+
    | id | serviceNodeId | ip_address   |
    +----+---------------+--------------+
    |  1 |             1 | x.x.x.x      |
    +----+---------------+--------------+
    1 rows in set (0.00 sec)

As can be seen in this example, the ip_pool table includes an entry regarding a nonexistent IP address ( ip_address_id = 2);

Delete this record from the ip_pool table:


    mysql> delete from ip_pool where ip_address_id=2;
    Query OK, 1 row affected (0.00 sec)
