The following bit of code randomly loads one of a small number of pages:

        $timeval = mktime();
        srand($timeval);
        $randval = rand() % $num_files;

        $file = $path . $files[$randval];
        if(is_readable($file))
        {
                $fp = fopen($file, "r");
                $pass = fpassthru($fp);
        }

Sometimes this code crashes apache(1.3b5) and causes the following
error_log message:

[Mon Apr  6 13:12:36 1998] [notice] httpd: caught SIGSEGV, attempting to
dump core in /usr/local/apache

User is no longer able to reproduce the bug, may 
have been fixed in the latest CVS

Most probably fixed, and nothing to go on either way...
