Hi Rick,
I think I have found the bug. Please check this commit
Hi Anand,
Every
time we switch DNSSEC on for a single zone, it iterates over
all
zones (and logs something trivial about each).
What does it log?
info: [ZONE] DNSSEC, signing zone
It's as if it iterates over all signed zones and touches it lightly,
but
for many zones this introduces a seconds-long delay (and it seems like
a
waste).
