please check your use of disk space on hemlock. in a quick perusal of home directories i have found several logfiles which are hundreds of MB in size, and could surely be trimmed a little. i suspect there is a lot of other wasted space.
the worst offenders for disk usage (>1GB) are:

obviously, don't delete anything you're actually using. just make sure that things you don't need anymore aren't wasting space.
