Server becomes unaccessible after hours.

Hi,

I installed Apache some time ago and all works pretty most of the
time. People, worldwide, can access the data that it serves.

But everyday my website suddenly becomes unvisible. Which are the
possible reasons?

Here my detailed observations:
--------------------------------------------
- DNS serve the right IP when typing the URL of my site.
- The browser tells that the server was found but the loading
progression bar is ultra-slow .
- No document is sent from Apache.
- Restarting Apache doesn't solve the problem.
- Stopping Kaspersky firewall protection doesn't solve the problem.
- Restarting Windows XP always solves the problem.

Might this be a problem due to Apache configuration?
Or maybe port 80 blocked to entries? How to know ?

Thanks for any help.

What do the apache access and error logs show when this happens? You
say the page is ultra-slow to load. Does it eventually load or does it
fail. What error does the browser report (if any)?

Re: Server becomes unaccessible after hours.

Hi,

To me this smells like a network problem, not something in Apache. Check
what happens by monitoring the packets that travel over the network. I'm
a huge fan of Wireshark (formerly Ethereal), but there are other tools
around.

Start Wireshark on your Apache server and monitor traffic to and from
port 80. Usually it doesn't take more than several tenths of a second
before a request is answered. See if requests that you send actually
arrive at port 80 and if answer packets are being sent out. You can do
the same test on the machine that runs your browser. Send a request and
see if anything comes back.

You can download Wireshark from http://www.wireshark.org/

Good luck!
