Unexpected Downtime

Had some unexpected downtime this afternoon.  ColdFusion's class file cache had completely filled the partition it resided on, locking up the box.   Deleting of all the files is still underway, but I've disabled the file-based cache so it doesn't happen again.  Everything is back up and running, albeit slowly as the system is churning away deleting several GB of little tiny classfiles, all in one huge directory.
