Accounting multicast + unacknowledge mode and conflicting packet

Our GGSN is configured to send Radius accounting in multicast to multiple servers and ignore accounting response (unacknowledge mode).
In this case, GGSN (which sends several thousand requests per second) reuses emitter UDP port and Radius ID pairs rather quickly.
On the FreeRadius side, we then encounter multiples cases of "Received conflicting packet" in the logs.
Would it not be possible for FreeRadius to process all Accounting, in this particular case where the GGSN is configured in unacknowledge mode?
