Dettach problem

Hi all, I would like run a php-script via CLI which outputs some information to stdout, and then go into background. I use code similar to this to fork and to dettach the child I/O from the TTY (some error handling removed to improve readability) <? echo "Hello from parent\n"; if(pcntl_fork()) { exit; } posix_setsid(); fclose( STDIN ); fclose( STDOUT ); fclose( STDERR ); if(pcntl_fork()) { exit; } echo "This message should NOT go to stdout of parent process\n"; ?> It works fine using PHP version 5.0.4, but when using PHP version 5.1.2 the output of the child ("This message....") goes to stdout of the parent process. So if I do: php test.php >output Using PHP 5.1.2, the file contains: --------------- Hello from parent This message should NOT go to stdout of parent process --------------- Can anybody explain this? I run FreeBSD 6.0-RELEASE... Regards, Grape
