php include problem

[cosmin]

Hello!
Few times/day I receive this error:
Warning: main(http://www.domain.com/include/textad.php) [function.main]: failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden in /home/evrika/public_html/anunturi/cauta.php on line 185

Warning: main() [function.include]: Failed opening 'http://www.domain.cominclude/textad.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/evrika/public_html/anunturi/cauta.php on line 185

After Apache restart all works fine but after few hours again the same error.

Any ideea?
Thank you very much!

apache may need a recompilation. try it.

I try few times.... Other solutions?

Actually that looks more like too many simultaneous server connections

I would do a "netstat" in SSH when you see that problem occur and also
view your "Apache Status" in WHM.

That should give you a much better idea what is really happening.

I am having this exact same problem.

If it is as Spiral says (and I think it is) ...Too Many Connections... how can this be fixed? My server has a very light load on it, and I only have about 15 low-traffic domains on it, so I'm wondering if there's just a bad setting in WHM somewhere?

Here's a perfect example of the issue... I've installed a program that crawls the site and creates a Google sitemap. When I run the program I get the same error as above. So I kill that program, and restart Apache, and the problem disappears.

Cannot speak for the original poster, but I'm running CentOS 4.2, PHP 5.1.6, and WHM 10.8. Dual processor, 1GB.

Looks like both of you are on the same slate.

what is your connection limit in apache?
MaxClients
/usr/local/apache/conf/httpd.conf

You may need to increase the connection limit and perhaps lower the timeout times and TTL accordingly.

for total unique users:
netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n | wc -l

for connections by each user:
netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n

Thank you Jayh38. Good info there. I will check those netstats next time the problem arises.

As for TTL... is that the same as the "Domain Time To Live" setting on the WHM page:
Server Configuration >> Basic cPanel/WHM Setup

If so, my setting is 14400.

My "Nameserver Time To Live" is 86400 though. Do those sound like decent settings? What else might you recommend?

As for max users... can that be accessed through WHM too? Or only through SSH?

Thanks!
