[vtk-developers] [Paraview-developers] change to vtkExodusIIReaderPrivate::ResetCache()

[Robert Maynard]

Hi,

The changes to the ExodusII reader was made to reduce memory overhead in
ParaView. If you set the cache to any positive non zero value does the issue
go away? Also would you be able to provide a sample data set that replicates
this issue, as all my ExodusII sample datasets have no issue with the cache
size set to zero.
