[Pdns-users] Bad cache TTL with pdns-resursor

[Michael FROMENT]

Hi,

I have some strange cached TTL on my pdns-recursor ( version 3.2-4 under
debian ).
When I query my recursor the TTL doesn't decrease by 1 second. Moreover the
TTL never goes to 0 so the zone never expire in cache.
As an example:

root at BBK2NS:~# dig soa google.com @89.2.0.1
;; ANSWER SECTION:
google.com.             569     IN      SOA     ns1.google.com.
dns-admin.google.com. 1472387 7200 1800 1209600 300

Is this a known bug on the recursor?

Kind Regards
