Thanks, In my case:
   
  mminfo -r 'name,client,ssid,savetime,ssbrowse,ssretent,level,ssflags,state' 
-q volume=000042
 name                          client     ssid         date    browse   retent  
  lvl ssflags
/data0                         a11ns00.jtc.jcvsf.org 2961855113 06/10/06 
09/10/06 09/10/06 2 vrENF
/reseq-nhgri                   a11ns00.jtc.jcvsf.org 2995409458 06/10/06 
09/10/06 09/10/06 2 vrENF
/sge                           a11ns01.jtc.jcvsf.org 2894750007 06/10/06 
09/10/06 09/10/06 full vNF
/tcag-work                     a11ns01.jtc.jcvsf.org 2877972986 06/10/06 
09/10/06 09/10/06 full vNF

  Shows that savesets /data0 and /reseq-nhgri have expired, but /sge and 
/tcag-work have not, and they show up as browsable in the GUI, hence they won't 
expire while browsable.
   
  In the case of the /sge saveset:
  mminfo -va | grep sge | grep full
000024         a11ns01.jtc.jcvsf.org 09/29/06 19:00:03 7141 MB 320710055 cbN 
full /sge
000042         a11ns01.jtc.jcvsf.org 06/10/06 02:01:03 6063 MB 2894750007 cbN 
full /sge
000088         a11ns01.jtc.jcvsf.org 07/08/06 04:30:31 6909 MB 78605637 cbN 
full /sge
000118         a11ns01.jtc.jcvsf.org 08/05/06 01:32:49 6964 MB 3335794049 crN 
full /sge
000178         a11ns01.jtc.jcvsf.org 09/01/06 19:00:02 7049 MB 1022933921 cbN 
full /sge
   
  Shows that I've done 4 full backups since the original one on 6/10/06.
   
  And, 
  mminfo -va | grep 2894750007
000042         a11ns01.jtc.jcvsf.org 06/10/06 02:01:03 6063 MB 2894750007 cbN 
full /sge

  Shows that for that saveset ID, this is the only volume that it resides on.
   
  All of this is why we (+EMC/Legato) are pretty confused as I could go ahead 
and manually expire (recyclable) this volume, but what we expect is for it to 
auto expire.
   
  Some other volumes have been autoexpiring, but I've got 8-9 that should but 
haven't.
   
  Thanks,
  Randy
   
  PS: I'm not meaning to hijack the OP's note, but since these issues are quite 
similar I thought I would go ahead and reply.

These issues almost always come down to a misunderstanding of how 
retention policies and save set dependencies work.
Howard has explained perfectly what the original poster's problem is. 
Yours is probably similar.

It is not the volume that expires, it is the save set. If the save set 
depends on another save set in order to correctly allow a point in time 
recovery to meet the specified retention policy, then it will not 
expire, hence the volume containing it will not become recyclable.
