UNIX for Dummies Questions & Answers

I host a few websites for friends and lately my server has been bogging down at times. I think that it is because of a dns conflict. Someone said that by doing a nslookup I should be able to see it and then do a pkill -9 in.named and then do in.named to get it going again.
Any feedback on this greatly appreciated.

With only this amount of information, it's hard to say anything useful. A well-behaved named should not hang like that; if you can find out the root cause for that, we can talk about the problem in more concrete terms.

If your named stops serving requests, nslookup will time out; obviously, no web traffic to the server can take place by using the server name in that situation (whereas requests by IP address should continue to work, as such).
