Oh, I meant a os kernel bug; no way to hotload those.<p>I have two servers, if I get two carpable ips, and may each server primary on one, and put them both in DNS, I have load balancing and failover. If I just use one IP, at least I have failover, anyway I need each server to be able to handle full load, so I could have hot-warm instead of hot-hot.<p>(with more than two servers, need to figure something else out, probably two boxes running a simple load balancing in front of the rest of the cluster.
