PROBLEM: (85995) (PATCH ID: OSF440-971)
********
sed gives exit status 0 when the disk is full. There are two cases to be 
considered when the disk is full. (1) When target file itself cannot be created.
(2) When target file can be created, but data cannot be written to it.
The shell take care of the first case and exit with value 1. This fix, takes 
care of the second case.
