Nope.  (And I want to emphasize that Ubuntu clients don't exhibit the
problem, so whatever it is, it doesn't appear to be related to the
backing filesystem on the server.)

You really need to get some server-class hardware.  Perhaps the
Foundation can help?

I'm currently using the following command, which seems to reproduce
the problem reliably on my client and server:

bonnie++ -s 0 -n 144:0:0:1:16384 -u 4294967294 -D

This minimizes the amount of temporary storage required.
