Server becomes io-bound on no disk writes.

compdoc,

I am trying to find support to track down the cause of the spurious disk 
writes that force the server into an io-bound state. Now is not the time 
to be doing hardware benchmarks. Ask me again when the issue is resolved 
and I would glad to provide such benchmarks.
