Closed as program error.
When the Algorithm First-Alive on a DNS server is configured and the DNS server responds to a query with an additional RR (resource record) DataPower may disregard the Answer record response
Consider a different load balance algorithm or configure the DNS server to no longer respond with additional RR.
Affected is DataPower use of DNS in configurations using DNS name resolution, with DNS using first-alive algorithm. When DataPower obtains a DNS response containing a zero-length response record, it will fail to parse the response, failing the corresponding hostname resolution. An example of such DNS responses are ones containing an empty EDNS0 extension record.
Fix is available in 22.214.171.124 and 126.96.36.199 For a list of the latest fix packs available, please see: http://www-01.ibm.com/support/docview.wss?uid=swg21237631
