Some “security” software (e.g. firewall and anti-virus programs) will interfere with the inheritance of socket descriptors between processes. One such program is the ZoneAlarm Security Suite. Another is NOD32. I don’t know if this is an intentional security “feature” or a design flaw. If you have this (or similar) software installed, it may need to be disabled or completely un-installed for socket inheritance to work again.
