I have seen this before and I believe it has been reported to this list
before.  I don't recall seeing a fix for it.  After recent having a pile
of these, I did some guess work on the cause.  My gut feeling is that
the *MSG handling routine is opening an interrupt window where it shouldn't.
And that two messages pop in at very close to the same instance (being a
core site, this is not to unreasonable).  Something happens and something
gets released twice.  Currently (as of several days ago), I'm trying an
experiment to see if this is the cause.  Since MAILER is registering for
both SMSGs and normal MSGs, it is getting all those RSCS file sent messages
(as well as "normal" messages that other servers send out).  I have done
a "SMSG MAILER CP SET MSG ON" (or OFF, if you wish), so that messages
will no longer be sent to *MSG via the IUCV setting.  You may wish to
try this and see if this improves things for you.  I would be interested
in hearing if it does.
