  I don't think that rsync was the problem. Do you have 
  evidence that rsync causes machines to go down? Surely
  last time it did, but the problem was not rsync.
  the problem was JMBC shoehorning 100000 files into
  a single directory. If you had transfered these with
  ftp rather than with rsync, you would have gotten
  the same trouble.

  I hope that your theory is right that having large
  directories is the problem. In that case, as you 
  wrote, we need to get a larger disk.

  Bob send you a disk for nebka. You diverted it to
  IDEAS. Before we proceed, put that disk into nebka.
  Or if you can't do that, go to the shop, buy a 
  500 Gig PATA disk for $150 bucks. Then ask Bob,
  he seems to  know about a device that can case
  these disks and has a USB interface, connect via USB.
  Buy that device, put the disk into it and hook it up
  to the machine. We then move /home off to the new disk.
  To move /var it is best to work in single user mode 
  (second entry on the grub screen). We can do that
  later in a scheduled downtime.
