Hello Nikos I have memory leak issues when creating animations from an XDMF file from the Paraview GUI (version 3.14.1 32-bit). In my case, I was using a single file XDMF file pair (i.e., one XML file and one HDF5 file) rather than a series of XDMF files.
As a workaround, I use VTK to write a series of images and then make the animation from those myself. I wonder if there is a memory leak in the Paraview 3.x XDMF reader? I think Kitware may have used a new version of the XDMF library in the recently released Paraview 4.0 ... if so, then you might try Paraview 4.0 to see if that fixes the issue.
