If a client destroys the cm_id immediately after sending a DREQ (before the 
DREP is received), the CM will transition the cm_id directly into the 
timewait state.  I've just committed a change to the CM to cancel the DREQ 
if the cm_id is destroyed.  Note that this won't result in the DREP matching 
with the DREQ, since the cm_id has been destroyed, but should prevent the 
DREQ from being resent, if this is indeed what is happening.  Can you pull 
the CM from 2485 and retest
