I'm not a forkin' expert.. but on one host I did have a problem using the technique I described, and ended up having to force a "clean" environment by wrapping the whole thing in an env:

exec("env -i /path/to/php /your/script.php 2>>/your/logfile.log >&- <&- >>/your/logfile.log");

so something "bad" was being inherited by the process...
