Hi, i got some trouble with a PHP script using pcntl_fork do run some work in background. Runnig my script on my development system (PHP version 5.3.3-7) it behaves like intended. But running it on my production test system (PHP version PHP 5.1.2), i got some strange results. The problem is, that when i logout from my SSH session the console closes not properly, like somethings is kept open. Sadly, updating this old PHP version is not a option... :/ Does anyone have an idea whats going on? Thanks in advance Ralf The script is this: #!/usr/bin/env php <?php $pid = pcntl_fork(); if ($pid == -1) {

      die('Fork failed!');

} else if($pid> 0) {

     exit(0); // close parent process

} else { // child process:

     while(true) {
         sleep(10);
         // do your work -- stripped
     }

This sounds more like an OS issue then a PHP issue. What are the two OSs involved? -- Jim Lucas http://www.cmsws.com/ http://www.cmsws.com/examples/ http://www.bendsource.com/
