The point is that LISTSERV doesn't know that CODE_1.5K is obsolete before it reads it (ie it doesn't attach any semantics to the shipment name).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 :-) Eric
