A weird problem - http dies then comes back again itself.
I am running centos, dedicated server. no cpu load, running a couple of sites on the server.

Now what happens is the following. All sites running fast, no lag. Suddenly I cannot connect to them, and after 1 minute or so, then I can connect again and every thing is fine.

Happens quite often, what should I do about this problem?

Well first,
What are you running? (Versions and build dates if you have them)
You mentioned CentOS but did not indicate what version, or which kernel, etc.

What are you running on (hardware or virtual, if hardware can you describe it)?

Have you examined the system logs, application logs, and tried to research any errors or unusual messages?
