>Hmm. Not sure why does CM need to do this? Does it say so in the spec?

>From 12.9.8.3.1:

(RC, UC) A CM may receive a REQ/REP specifying a remote QPN in
"REQ:local QPN"/"REP:local QPN" that the CM already considers connected
to a local QP. A local CM may receive such a REQ/REP if its local
QP has a stale connection, as described in section 12.4.1. When a CM
receives such a REQ/REP it shall abort the connection establishment by
issuing REJ to the REQ/REP. It shall then issue DREQ, with "DREQ:remote
QPN" set to the remote QPN from the REQ/REP, until DREP is received
or Max Retries is exceeded, and place the local QP in the
TimeWait state.
