On the assumption that it's getting overloaded, I fired up iozone,
it pumps out 6.6 - 7.2MBps to the netapp, for as big a file as I had
free space, w/o generating the error.

I notice that it's specifically tied to INN, if I shut off innd, I
don't get the error, regardless of the combo's of diskex, iozone, and
bonnie I run.

Turn on INN, wait a few minutes, and shazam.
