That is most curious. How much actual swap is available? My RPI3 is 
killing jobs with "out of swap" despite 4 GB in three physical partitions, 
one on USB flash and two on the microSD card. Both storage devices are of
the same type (SanDisk Extreme) and have similar write speeds, likely
better than NFS via the usb-ethernet adapter.  

Thanks very much!
