I'm sorry!
I did a mistake!
The "tar" process didn't stop for "file changed as we read it " error.
But I am sure that the file doesn't change during 'tar' process.
The 'tar' process finished but the error caused an exit status error (in 
particular =1).
This situation, in my script, cause a script termination.
Now, I should manage this situation.

Thanks at all
