I had the same problem and offsitereclaimlimit=20 (or whatever you want
to limit it to) worked for me.

In my particular situation my server is 5.4.1.0 (I know, very old!)
running on AIX 5.3 (5300-09-01-0847).  I have a few (less than 5-10)
tapes at a 99% reclaimable level in my offsite COPYPOOL01 tapes, but
about 500 tapes that are 98% reclaimable.  If I do NOT specify a
offsitereclaimlimit number it seems to process tapes to reclaim at about
3 tapes per minute.  So for 500 tapes it just sits there for about 3
HOURS before it even starts mounting tapes to start the reclamation.

 I stumbled onto how useful this particular option was about  3 or 4
months ago thanks to this forum, before that I didn't have a clue what
it was supposed to be used for.  Limiting it to 20 tapes lets it
actually start mounting tapes and moving files in about 6 or 7 minutes.

I also noted that in a recent posting in this forum, IBM has fixed the
order in which tapes are reclaimed, and if you specify something like
90%, it will start with 99% first, then 98%, 97%, and so on until it
finishes or runs out of time.  This solves my biggest gripe about
reclamation that I have had.  I have two new servers that will soon be
in production, and they are running the 6.2 TSM, so they should reclaim
much faster.

I started a reclamation on that pool yesterday afternoon and it sat
there for several hours before it finally started moving anything. 
I guess I got behind doing the reclamation. But that doesn't make any
sense because the offsite pool and the onsite pool have the same
settings and the same content. Only difference is that one goes off
site. 

I use the same settings when I run reclamation on both pools but I run
them at completely different times and the times don't overlap. When I
run the onsite copypool script the process starts without delay. The
same settings for the offsite copypool takes forever to actually kick
off. 

I guess I'll need to keep a closer eye on things........

Try running one at 99% and _no_ time limit, and expect it to run for
days.

There's a huge amount of bookkeeping work TSM does at the outset.  If
you've gotten yourself stuck somewhere, and lots of time has passed,
you may have a large backlog.  In that case, trying little nibbles is
the only way to go.

You could also approach this from the

-OFFSITERECLAIMLimit--=--number_of_volumes-

side, limiting it to just a few at a time.
