If it turns out that this output log file is not the culprit, here's a 
command that I use to look for large directories:

find $1 -mount -maxdepth 4 -type d -mtime -7 -exec du -s {} \; | sort -rn

Note that a directory's size includes the size of all its subdirectories 
too, so first-level directories are bound to be larger.  Look for second, 
third, or fourth level directories near the top of the list.
