virtual domain limit?

[mnolan () southshore com]

Hi,

Our web server is running Red Hat 5.2 (Linux).  

We were recently told that we have exceeded the limit number of domains
on our system.  We haven't been able to contact our tech support person 
since then to get a clarification.  We recently added four domains, and 
our web pages promptly went down.  He said that we had 167 domains and 
the limit was set to 165.  Actually we only have 78 domains.  This is 
really confusing.  I do know that we are running all our domains off one
IP using the NameVirtualHost directive in httpd.conf

Does anyone know anything about a limit of domains setting?

Any help would be appreciated.

Thanks,
Mike
