Severity: 3-Major


If dns profile with "Unhandled Query Actions" set to "Reject", dns queries could return successfully every other query and REFUSED every other query too. If dns profile with "Unhandled Query Actions" set to "Allow", dns queries might return differently for wideip and its alias


DNS queries might get REFUSED even though there are other pools available.


1. Wideip contains some UP and some DOWN pools. 2. Return2DNS LB method configured as failback for pools.


Modify the pools to use 'none' as the Fallback Load Balancing Method
