Apache Crashing due to 500 sessions to 0.0.0.0

| Hey everyone
I am having an issue with Apache on my cpanel server crashing. When I look up the the sessions it shows 500 connections to 0.0.0.0 (or default route).
I contacted my hosting provider and they explained it is due to customers code. I.e. they reference urls via domain httpwwwdomaincom/something.html vs directory structure ie /home/public_html/something.html. Personally, I don't think this is the reason for the server crashing. There is no way to make sure that all customers use the directory structure in their code. I cant reference urls since I am a new user.
Personally, I have plenty of pages hosted on a popular shared host running cpanel and I have referenced domains in code without the server going down.
What could cause this? How might I fix it?
I am running CentOS 4x with cpanel 11 + WHM
Thank you for any help you can provide.

| Try turning off allow_url_include and allow_url_fopen, and see how many connections you get

| The absolute url does open more connections to the server when called. If more users access the site more connections are made. Try increasing the MaxClients value in apache.

| Is it advisable to block incoming connections from 0.0.0.0 in the firewall?

| No, that would not be advisable.

| What could be the problem if we block the incoming connections from 0.0.0.0?

| This would mean that no connections would be accepted from any IP address on the server.

| 0.0.0.0 signifies a binding to all the IP addresses that the system/interface has available. I'm not sure what a connection to 0.0.0.0 might be in technical terms, but Apache binding to 0.0.0.0 means it's listening to all available IPs.
