RE: [PHP] Question about exec() call an CLI php script from Apache CGI/filter module PHP

I forgot to mention that calling from shell directly s.php runs correctly. ~~~~~~~~~~~~~~~~~~~~~~~~~ marvin:~/liang.ns2user.info/php> ./s.php This is a PHP-CLI Script!!0123456789 ~~~~~~~~~~~~~~~~~~~~~~~~~ The php configuration of this site is: http://liang.ns2user.info/php/info.php Thank you in advance. Liang

I call red.php through apache http request, and red.php make exec('./s.php') call, then I got bunch of s.php processes, and system locked me out any task due to no more processes available. Why this would happen? marvin:~/liang.ns2user.info/php> less red.php <?php ignore_user_abort(true); header("Location: redirect2.html"); exec('./s.php'); ?> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ marvin:~/liang.ns2user.info/php> less s.php #!/usr/local/bin/php -q <?php echo "This is a PHP-CLI Script!!"; for($i=0;$i<10;$i++) { echo $i; sleep(1); } $fp = fopen("/tmp/foo.txt","a"); fputs($fp,$i); fclose($fp); ?> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ marvin:~> ps -u liang
