Closed as program error.
If the Load Balancing Algorithm in the DNS Settings is set to Round Robin, the TTL (time to live) setting might not be honored. The DNS resolution caches for lifetime.
In the WebGUI, go to Network > Interface > DNS Settings and change the Load Balancing Algorithm from Round Robin, which is the default value, to First Alive.
Affected are all DataPower appliances that query DNS servers and obtain responses to AAAA query with OK response code, but no address records. This includes appliances with no IPv6 networking configured. Only configurations using DNS with round-robin algorithm are affected. The appliance always sends out both A and AAAA DNS queries for every DNS name it does not hold in its cache. Depending on the mutual timing of the DNS responses to these queries, a DNS cache entry with invalid TTL value may be created. That invalid TTL may be long or virtually infinite.
Fix is available in 184.108.40.206, 220.127.116.11 and 18.104.22.168. For a list of the latest fix packs available, please see: http://www-01.ibm.com/support/docview.wss?uid=swg21237631
