Hi!
a linux gentoo with golang v1.7.3, grimd v1.0.2

The default configuration file.
After some time, no longer be given zone.
Here he writes in debug mode:

[GIN-debug] Listening and serving HTTP on 127.0.0.1:8080
start tcp listener on 0.0.0.0:53
server.go:45: start udp listener on 0.0.0.0:53

handler.go:192: ya.ru not found in blocklist
resolver.go:61: ya.ru resolv on 8.8.8.8:53 (udp)
handler.go:240: insert ya.ru IN A into cache

over time, domain it's not resolve :

handler.go:128: ya.ru IN A hit cache
handler.go:84: 192.168.1.10 lookup　ya.ru IN A
handler.go:90: Found ToggleName! (cache-stav01.cdn.yandex.net)

handler.go:90: Found ToggleName! (export.yandex.ru)
activation.go:42: Toggle is too close: wait 10 seconds
what could be the problem?
that can then be added to the configuration?
Thank you!
