asterisk users - Oct 2004 - meetme caused 'RTP Read error: Bad file descriptor'

Hi all,

Yesterday I had an * server stop working.  The triggering event was a 
caller being transferred to a meetme room:

    ---snip---
     DEBUG[14270483]: Released clone lock on 'SIP/299-731b'
     DEBUG[14270483]: Done Masquerading SIP/211-8649 (6)
     DEBUG[14270483]: Ooh, something swapped out under us, starting over
     WARNING[14270483]: Error getting conference
     DEBUG[14237713]: Bridge stops because we're zombie or need a soft 
hangup: c0=SIP/299-093a, c1=SIP/299-731b, flags: No,No,Yes,Yes
    ---snip---

followed immediately by the following warning repeating 
_hundreds_of_thousands_ of times (in an 8 second timeframe):

    ---snip---
     WARNING[14270483]: RTP Read error: Bad file descriptor
    ---snip---


The server is running * 1.0-rc2.
Any idea what would cause this?  Has anyone else experienced similar 
behaviour?

Thanks
Ryan
