Is the script in question a php script?  Check the error log
(/var/log/httpd/error_log). I suspect you are hitting the limit of
database connections, which would make the script error out.

5 or 6 hits per second is a pretty low limit. You need to figure out where in the client -> Apache -> PHP -> MySQL chain your getting clogged up. As Charles suggested, watch your error logs. Your PHP error log might end up somewhere else, depending on the error_log directive in php.ini.

In your apache config, maybe check your MaxClients and ServerLimit parameters.
  http://httpd.apache.org/docs/2.0/mod/mpm_common.html#maxclients
  http://httpd.apache.org/docs/2.0/mod/mpm_common.html#serverlimit

Open a mysql client while you hit this page, and run 'SHOW PROCESSLIST;' every few seconds. You'll see all the currently-running queries, and how long they're taking. You have some badly-optimized query which is slowing the whole process down. If you want to do this frequently, Google for mytop, which is like top, but for watching a MySQL server.

That, or
hitting a php memory or execution limit, all of which can be fixed by
tweaking the php.ini or my.cnf.
