recently I'm facing this issue which is more or less than two weeks that I've noticed but didn't take any precautions.
So I have a bind server (version 9.3.4-P1.2) running on a Debian 4.0 server.
The named process keeps wasting high cpu usage, averagely more than 50% all the time. Before it consumed less than 20 %.
The server is updated with the latest packages (apt-get update), and I don't know if it is a bug.
Can you help solving this issue.
