Jean,
the problem is described in APAR IC21764 and it came through changes in the
ADSM internal representation of national characters.
We waited lots of months but finally Andy Raibeck created a very fine tool
to cleanup the filespaces. We've tried it out and it works very well,
cutting 30000 error messages per night down to zero.
I haven't seen the tool in the fixtest ftp directories yet, so I don't know
anything about the official availability.
 
Regards,
Michael
