The point is that LISTSERV doesn't know that CODE_1.5K is obsolete before
it reads  it (ie it doesn't  attach any semantics to  the shipment name).
What happens is you had, at  some time, a CODE_1.5K shipment which didn't
install  because of  a pre-req  error. Then  the spool  file got  trashed
somehow (either  you or  your spool  cleaner purged it,  or maybe  a cold
start did).  LISTSERV still  remembers that it  has "some  shipment(s) to
retry when RELEASE  becomes > 1.5k". This has happened,  and the shipment
is  being marked  as "to  be retried".  Since it's  lost, LISTSERV  can't
determine that it's obsolete.  You can get rid of it  by doing an INSTALL
CLEANUP CODE_1.5K. The INSTALL code is  not supposed to be very smart nor
user-friendly, and doesn't contain much bells&whistles :-)
