disclaimer -- cannot tell for sure. Still, since /dev/nst0 is, to
tar, "just" a file and so it needs to call close(2) I'd suspect
a tape (drive) problem since this system call cannot fail for lots
Some things I'd do ...
dmesg - any messages from the driver
tape - try a different one
dirt - does the drive need some cleaning and some, like this here,
can warn you with a certain sequence of blinking of its
LEDs and using a vacuum cleaner is helpful to get rid of any
Hope it helps,
