 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.
