Only 15 subdomains

[scs]

Hi guys!
At first sorry for my english. It's not the best of mine.
And of course I'm a new guy here, so if I make a mistake, please be permissive.

I need some help in subdomain creation.
I have a VPS with DirectAdmin, on Ubuntu. My website will have some subdomains and they are redirecting to the main directory with this (in the /etc/httpd/conf/httpd.conf file):

<VirtualHost 123.123.123.123:80>
ServerName domain.com
ServerAlias *.domain.com
Documentroot /home/user_directory/domains/domain.com/public_html
</VirtualHost>

(it is an example)

With this I can create 15 subdomains (on the DirectAdmin panel), and they're working well.
But when I want to create a new subdomain (16. or more), it will have a trouble. The subdomain-directory in the domain-directory is created well, but I can not reach the new subdomain on the Internet ("Adress not found").

- I thought that there is a problem with the DNS, but testing with dnswatch.info it's OK - it gives back my IP adress well.
- Then I thought that the problem is in the .htaccess redirection, and I enlarged the RewriteOptions MaxRedirects=10 to 30, but it can't solve the problem.
- Of course in the DirectAdmin panel I can create unlimited subdomains per domain, so this is OK.

And now I arrived here.

Please help me, if you can. Thank you in anticipation.

Nobody knows? Or my english text was too difficult to understand?

Your english works. Did you create the subdomains on DirectAdmin? Or just rely on having a single IP#?

Oh sorry, I forget to say, that the problem was solved. It was only a funniness. Two days before I created more subdomains, and they didn't work. Yesterday they did. I think, the problem was the DNS refresh. It should refresh in 5 minutes, but it was almost one day.
Thanks.
