Strange Problem:::Help me please
Hello,
We're having a strange problem one week ago. Suddenly we can't acces some domains and server returns 500 Internal server error.
We can't access domain.com or domain.com/directory.
We can't access domain.com/cpanel
But we can acces domain.com:2082 or domain.com:2087
This problem appear and disappear after 4 or 5 hours.
We have rebuild apache, update cpanel , reboot the server but the problem didn't disappear.
DC help support hasn't benn useful
Could anybody help us?
Thanks

Did you make sure your firewall isn't blocking port 80? Also make sure apache is set to listen to port 80. (ie: Listen 80 in httpd.conf)

Hi there,
Are you trying to install Modsecurity? If you do, make sure you used the correct ruleset because if you don't, it will restrict access to Apache and thus the 500 error message appears.SecureAX Singapore - Virtualization, Private Cloud Computing & Managed Datacenter in Singapore

Are the said domains over their bandwidth limit? Some time ago cpanel replaced the bandwidth exceed page to show 500 error instead.
Why do they call them fingers? I never seen them fing. Oh, there they go.

We tried all commands with cpanel : fixquotas fixeverything fix perl... but not positive.
More suggestions are welcome.
Thanks for your help.

We can't access domain.com/cpanel
But we can acces domain.com:2082 or domain.com:2087
When users access /cpanel or /whm or /webmail on their domain redirect them to the https(ssl) port instead of the insecure one
Make sure you check that option then save setting
That is useful although not helping you directly but access account manager in SSL-enabled is a plus to me.
For your Error 500... is it all accounts or some? If it is some, is it php script or cgi scripts or both?
Just my thoughts ... ...Last edited by choon; 03-20-2004 at 09:45 PM.

we had the same problem on a server, try this
"Modify Apache Memory Usage"
it was somehow related to the memory usage in the httpd.conf set to small. Might work, might now. Worth a shotSteven Ciaburri | Industry's Best Server Management - Rack911.com

Ohhh....my good. It appears a DNS problem returns 500 Internal server error.
We tried one hundred time but now appear to work through IP: 69.XX.XX.XX/~username.
Dnsreport.com returns problems when site returns the error:
FAIL Missing (stealth) nameservers
FAIL Missing nameservers 2
Could somebody to explain how to solve this errors? And the most strange, why returns an 500 Internal server error and why does it go out and come back?
Thanks a lot of to all yours.

If you are trying to access cgi scripts using http://ip/~username/cgi-bin/script.cgi... you will get error 500 for certain setting of your web server apache. Try normal HTML page to see whether the page load or not with or without any error. For script testing, please wait until the domain is pointing to your name servers and fully propagated. Then you can try it using the real domain URL without the /~username/
Just my thoughts

Why does a DNS problem returns the error 500??

Even for normal html pages? Have you try:
Code:/etc/rc.d/init.d/httpd configtest

Yes, this problem appears with html pages.

Yes, our nameserver are working. We use nslookup and it's fine.
The problem is with the domains what have a shared IP. No problem with others domains

You've checked resolv.conf to make sure you're using your IP's and your IP's only?

Yes, this file is correct.
Apache only return what files don't exist.

check if you have an .htaccess file with wierd directives in the root directive for this account...
If html is getting server errors, not just php and cgi, then something is probably off in .htaccess or httpd.conf

We had to say DC guys to use our one hour support to investigate our problem.
Now after having this problem for 5 days and investigate 8 hours, they told us:
We are checking on our DNS setup, as it appears people are having trouble resolving the DNS for your sites.
