Lars fixed the vmem starvation, but the processes hanging in "uvn_fp2
wait" supposedly nfs related issue remained.
We eventually replaced the machine in question with different hardware
and OS (Illumos), and repurposed it for light duty with its original,
more benign SCSI MegaRAID 320-2 controller.
The 320-4X with four spare drives is still in the machine, so I could
try out any suggestions.
