Severity: 3-Major

Unable to use snatpool for cache resolver.
1. dnscache.matchwildcardvip is enabled 2. Multiple possible routes to destination DNS server exist. This can be triggered by either using a gateway pool, or using dynamic routing with multiple equal paths available.
Ensure only a single route to destination exists, or disable dnscache.matchwildcardvip NOTE: With dnscache.matchwildcardvip disabled, snatpool will not be used.
