Or try to find the culprit with lsof (can't remember the options). You will see some processes using files you don't have -- kill that process and your space will be freed. I hope this helps.

The math used in df is a compromise. The system reserves about 8% of
the blocks in the filesystem for root to write only. This is because
back in the day if the filesystem truely completely filled up the
situation would go from bad to worse pretty quickly. If I recall
correctly The filesystem performance falls off of the cliff once the
filesystem fills up.
In your particular case I can see that you have about 150Mb free on
the system. You do have the option of getting at this space using the
tunefs command:
man tunefs
to change the percentage of free space reserved for root but as I
inferred before expect performance to suffer.
A thread poster suggested that you remove the contents of /usr/ports/
distfiles to free up some space. If you built the system from scratch
and have built a bunch of ports this is a good place to go but if that
is the case you probably want to clean out any work directories first:
# find /usr/ports -type d -name work -print
Will generate a list of the work directories for any ports you have
built. In general you can completely recreate this data by building
the port again so if you have a lot of space tied up here you can
easily reclaim it with this command:
# find /usr/ports -type d -name work -exec rm -rf {} \;
This will remove just the work directories from the ports tree. It
costs you extract, patch, and compile time but it's quicker than:
# cd /usr/ports
# make clean
If you haven't built the system from ports then you have to identify
what action filled up the filesystem and make the appropriate
correction.
