BFCREATE error during reclamation

Hi,

We are actually running ADSM MVS V3.1.2.40.
Every morning, we run expiration, then process of reclamation are launched.
We get the following error :

I have the error since yesterday many time, and always on these two tapes.

I don't know what it is, and what I should do to resolve this problem.
Any help would be appreciated.
Thanks in advance
