The CAM SCSI errors occurs in 4 different machines sometimes preceded
by the CPU error. It seems that this problem is trigged by our
backup software when writing to the tape.

The 4 machines has the same hardware configuration and run the same
software.

Drives and controllers were replaced with new ones but the problem
is still there.

TIA,

Christian.
