State-Changed-Why: 
That's normal behaviour.  The UFS filesystem reserves a certain amount
of space called the 'minimum free space treshold'.  This free space is
used to optimize write performance on the filesystem and to avoid
fragmentation.  The default value is 8% of the filesystem size.

Have a look at the tunefs(8) man page, especially the -m parameter,
for how to change this treshold value.
