Some how the volume big-0147 got corrupted (bacula bug? / kernel bug? / bad hardware? / other software? / unclean shutdown?) .

BTW, are you using a 32 bit OS? I have not had bacula on 32 bits since late 2004 at work. However I did have 32 bits at home till 2005. What version of bacula are you using? Are you using concurrent jobs?
