<div>Can I suggest you use IP addresses for a number of servers and see if they survive through your next episode. That will give you an idea of where the problem might be...</div>
<div> </div>
<div>It is the least amount of work towards identifying the cause.</div>

Subject: Re: [hobbit] wake up call<br><br><br><br> Hmmm... bummer, there goes that theory... If you are using IP<br>addresses, and you are still getting failures on these hosts, then dns<br>is not involved. A ttl of five minutes is fairly worthless for a caching<br>
server. It only helps if it hits the same device within five minutes, as<br>hobbit is pinging every five mins (default), you will most likely always<br>be pulling from your master/slaves...<br><br><br><br> Phil<br><br>
