Yup, that looks as though the tape is blank.

Have you tried btape and the command readlabel on that tape? Also, 'dd | 
od' or whatever flavour of that command you prefer can tell you if the 
tape holds a Bacula label. Then, finally, do you have system log 
messages regarding your tape drive?

 Any Ideas?

This looks suspiciously like the same kernel bug that is causing the system 
crash during my regression testing.  In an attempt to do better recovery in 
1.39.x I enhanced, to retry a number of times in 1.39.x.  However, doing so 
causes the crash, so be happy (if you can) that at least your kernel is not 
crashing.

My best guess is that the kernel SCSI driver either cannot get the memory it 
needs or that it has gotten terribly confused about size of the buffers it 
needs.

The error message you are seeing Cannot allocate memory comes from the 
kernel (probably the SCSI driver).

What OS and distro/version are you running?
