Posix and System V message Queue doubts

Sys V
-----
I have a C program named 'X' uses System V message Queue and communicates to a program called 'Y'.

Posix
-----
I have another C program named 'A' which unlinks a Posix Message Queue twice.  While first unlink, the original posix message queue is deleted.  When second unlink is made, the system V message queue described above is removed.

This issue happened in Production server, and I couldnt simulate the scenario.

Please let me know whether there is any relation between Posix and System V message queue handlings.

Usually, one is implemented in the terms of the other.

Another possibility, there is a common (OS specific) base
for both System V and POSIX facilities.

For example (AFAIK), Solaris threads and POSIX threads on Solaris (2.6, possibly) both are implemented in the terms of Light-Weight Processes (LWP).

Thank you JIEXA for your comments, I still need to explore on how both sys V and POSIX are related internally...
