[Paraview] Memory problems

[burlen]

Hi Mohammad,

I have recently seen leaks when processing many time steps using LIC 
rep, where the memory usage grows with each time step processed. This 
leak was either caused or exaggerated by having display lists on. 
Turning display lists off allowed me to process the 500 time steps. 
Unfortunately without display lists it's not interactive (5-10 min per 
render) so I switched to using pvbatch scripts. I reported this issue. 
http://www.paraview.org/Bug/view.php?id=12251 I don't know if that is 
the same leak you have experienced as I was using the LIC representation.

I have also had problems with the surface rep and seen similar behavior 
to what you describe with the surface represenation memory usage grows 
drastically (for 300 MB vector field consumption peaked around 8GB) and 
PV takes a looooong time to render. 9 times out of 10 ParaView crashes 
after this due to segfault not OOM condition. For me slice rep works far 
better rendering the same data very quickly. I filed a bug report 
earlier this week about this crash.

same issue.
