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.

Hi,
I'm just wondering if anyone else is also having memory problems with
PV 3.10.1 64bit on linux? It happens that when I use PV for a a couple
of days and I leave it open, for some reason it keeps consuming memory
and not releasing it even after deleting the objects in the pipeline
viewer. Another issue is when I zoom into a surface plot and PV starts
just using so much resources that eventually I have to kill the
process. I have witnessed about %40-50 on 8GB machine for a relatively
small dataset (~ 300 MB) and all I was doing was just surface plot of
some quantity.
I don't remember any such problem with PV 3.6 and 3.8 before.
