APAR status
Closed as program error.
Error description
When a DNS query returns a response larger than a single UDP packet, TCP will be used for resolution instead. If the request times out it is possible an unexpected immediate restart will occur.
Local fix
Problem summary
Affected are DataPower installations using DNS with round-robin algorithm, connected to an incorrectly configured server. When the DNS server response does not fit in DNS packet, DataPower DNS client retries the query via TCP as expected. If that query times out for any reason, the appliance might restart, generating a backtrace.
Problem conclusion
Fix is available in 6.0.0.14, 6.0.1.10, 7.0.0.7 and 7.1.0.5. For a list of the latest fix packs available, please see: http://www-01.ibm.com/support/docview.wss?uid=swg21237631
