[Paraview] slightly puzzled by paraview extract block behavior (UNCLASSIFIED)

had someone ask me for help with a problem they were having with paraview v4.1.0 in server/client mode.

steps are: i) read in an ensight case file, ii) use Extract Block filter to yank out a particular block,  iii) color extracted block with various variables.
simple enough.

let me say up front that the data is pretty small (order of 100k points, 450k cells).
we ran this using a varying number of procs in a single node.

when the number of procs got to be 14 or greater (16 cores in the server nodes) the extract block step lost the data variables.
the geometry was correct still but none of the data variables survived the operation.

I'll stipulate that it makes little sense to use more than one proc for data this small.

but why does the extract block not still work?

slightly puzzled.
