I know that it may sound silly, but I just discovered that LISTSERV (that is, LSVIUCV) will skip files which are either in user or system hold or have SFBINUSE on. In other words, when LSVIUCV tells LSVPROF to process file nnnn, this file has none of these bits on. It subsequently gets CP ORDERed, which ought to put it first in the queue and ought to make it impossible for RDR to even consider getting some info from other files. So, I'm starting to wonder if all this business is not simply a bug in the CP ORDER command, associated of course with the fact that RDR won't skip in-use files... A file which was not in use originally would be marked SFBINUSEd after execution of the ORDER command, possibly because some SFBLOK had to be paged in to move queue pointers, and then the bit isn't cleared *or* the ORDER command doesn't actually take place.
