sometimes, it's not how "advance" or "complicated" a script that could cause
problem, it's how understandable you are as to what those scripts does. for
example, your cgi scripts can be very simple but if you have lines like:
my @data = <FILEHANDLE>;
or:
if(/$reg/o){
#-- do something....
}
or stuff like that, your script will appear to be working most of the time
but it might fail once a while depends on what really came in. you should
look for those in your cgi scripts for anything that's obvious.

you could be right that your server might be overloaded but it's really hard
to tell except you are willing to tell us more about the platform, server,
your cgi scripts... etc before anyone can tell you what really cause the
problem
