I would look at the blocksize on each dataset in your concatenation and verify that you do not have any members blocked greater than the blocksize. A problem that I have had in the past was someone updating a PDS with a blocksize on the DD which causes the blocksize in the vtoc to be changed. I believe Ed and Ted are right about the largest blocksize first restriction on concatenations being lifted with MVS/ESA.
