Please don't run disk-intensive processes on zwinger, especially while we've got the crappy disk performance. The apaches slow to a crawl when somebody decides they've got to munge a few gigs of log files or whathaveyou and they can't get to the files on NFS.
I've disabled the webalizer job (again) and updatedb (which were scheduled to run at about the same time, making things extra bad).
