I see. This is the very same problem I've been trying to  track  down
for some time. See the threads stared by these postings:

No, I didn't find any of these messages. However, at the time of the tape full message the attached messages showed up in the syslog. Unfortunately I am not able to digest them into any correctional activity. But at least I understand that some hardware error may be involved.

No, this is most likely NOT a hardware issue;  I  have  this  problem
reproducable on several systems with different tape drives; it popped
up  suddenly  with  a software update, but that's not the only factor
that seems to play a role - the same software runs  fine  on  a  slow
system  (old  P  II 400 MHz box) but fails reliably on a fast machine
(Athlon 3000+). I see it with  different  SCSI  controllers,  and  at
least  with  bacula 1.38.5 and 1.38.6; my latest speculation was that
it had something to do with certain (pre 2.6.12) kernel versions, but
you mentioned that you're running FC5, i. e. a later kernel, so  this
does not fit.


I have those problems from time to time on a 2.4 kernel too (bacula 1.36.3)

Try running a plain kernel.org (i. e. non-FC)  kernel  -  and  please
report if this changes anything for you.

Best regards,

Wolfgang Denk
