Apache/Mongrel Cluster - What's this?

I’ve just set up a server with Apache 2.2, mod_proxy_balancer, and a
pack of Mongrels. I’m seeing something I haven’t seen before with this
setup. Here’s an example:

Processing StoriesController#index (for 80.129.122.251 at 2007-02-21
08:38:10) [GET]

[…]

Processing StoriesController#index (for ::1 at 2007-02-21 08:38:14)
[GET]

[…]

These are both for a single request.

It doesn’t happen on every request, even from the same client.

When it does, there’s a consistent 3-to-4 second delay between them.
Looks nasty in the browser:-)

Can anybody point me in the right direction?

Thanks!

If you’re referring to the ::1 address, that’s IPv6 notation. The
internet’s not quite running on that yet, but your local network might
be :wink:

I’d disable / turn that off for now. Sorry no links on that, what linux
flavor?

I guess I wasn’t clear. Yes, I’m aware that ::1 is IPv6 for “localhost”.

What I’m wondering about is why a single request would get sometimes two
responses, separated by 3-4 seconds. I’m sure I must have something
wrong (though I’ve used substantially the same config on another server
with no problems). But I don’t have a clue where to start looking.

Fedora Core 5.

Just thought I’d follow up, in case anybody else runs into this problem.

I checked my config, and IPv6 was not enabled on the server.

After scrounging around a bit in Apache documentation, I changed

listen *:80

to

listen :80

That seems to have taken care of it.
