OT:Server error.

[Javier Marcon - Servilink]

Hello, I have a sever with many vhosts running, but suddenly it become mutch more slower (in httpd and mail). I restarted the server and then apache takes a very long time to start and complies telling that 2 virtual hosts can't be reached. Before that, those virtual hosts worked fine. If I put in the browser the domain address of one of those virtual hosts that gave me error, it brings me another virtual host's page. How can I correct this?   Thanks.
