Message memory possiblly leaked?

[Rloase Flinne]

Hi there,
I've debugging my application which uses rtems message queue api's for
serval days. I knew that the messages are copied into rtems workspace.
Today after reading some source files I find that when I flush( using
rtems_message_queue_flush() ) a message queue and at the same time there
are some messages still pending on the queue, the messages memory
is not freed.

Could this be a possible memory leak? Do I miss anything important?

Thanks.
