Well, you may have a big enough disk, but one of your file systems is
not big enough or has too much garbage in it.  The most likely one
is the root file system (/).   

First use df(1)  to check your mounted disk file systems
  df -k        or  df -H    if you prefer

Then cd to the overrun filesystem (probably /) and use du(1) to
track down what is overfilling it.
Example:
  cd /
  du -sk *
    find three xxx.core files and /tmp  using up most of the space
  rm *.core
  mkdir /home/ofl.tmp        (for offload tmp)
  cd /tmp
  rm -r *
  cd /
  ln -s /home/ofl.tmp /tmp    

Now you should have lots of room in /

Alternatively, some people use /var/tmp for their /tmp or put it 
wherever they have lots of space.  I create a separate file system for it.
That way it is independant of other file systems having to be mounted
if I need scratch space while in single user mode.

If it isn't core files and /tmp, then you might have to pursue the
du checks a little farther down the directory trees.  Remember that
when you are in /, all the other file systems are rooted their.  You
only need investigate things that are not in the other file systems.
