The full error provides us some extremely useful context. Something cannot run the command /var/www/vhosts/cfhs69.com/cgi-bin/alumni001A.pl. Glancing at your website I'm going to bet that that command is what is run by Apache to serve the page http://www.cfhs69.com/cgi-bin/alumni001A.pl. Which tells me that the error message is almost certainly coming from Apache, and not your code.

Googling around I am willing to bet that it has to do with the problem explained in http://httpd.apache.org/docs/1.3/misc/FAQ.html#fdlim. Namely that your hosting provider is trying to run too many virtual hosts out of Apache, with the result that sometimes you get an Apache process that has opened up too many files, connections, etc and can't open another. (They may be using Apache 2, but the same issue still exists because it is an operating system limit, not an Apache limit.)

In which case the possible solutions are that they can raise the operating system limit as is documented there, they can run fewer virtual hosts per server, or you can find a more competent hosting provider.

PS: Please call the language Perl, not PERL. See the FAQ for verification. Calling it by the wrong name grates on people who are competent with the language. So unless you actively want to irritate people here, you really should call it by the right name.
