Hello, everyone!

I'm trying to enable dns_srv_lb but I'm stuck just before I can get there. If I don't enable use_dns_failover, lookups work and calls route but always to the first host. We need to load balance, so that doesn't work very well.

If I enable use_dns_failover, the lookups stop working completely and we get a dns lookup failure like so:

ERROR: tm [ut.h:296]: uri2dst2(): ERROR: uri2dst: failed to resolve "redacted.hostname.here.com" :unresolvable A or AAAA request (-7)

This works:

use_dns_cache=on

dns_use_search_list=no

dns_try_naptr=on

# use_dns_failover=on

This breaks it:

use_dns_cache=on

dns_use_search_list=no

dns_try_naptr=on

use_dns_failover=on

I have checked to see that use_dns_failover is compiled in:
