Hi Tobias,<div><br></div><div>Could you please submit a bug at <a href="http://paraview.org/Bug/bug_report_page.php">http://paraview.org/Bug/bug_report_page.php</a> for the memory leak in XMDF/HDF5 files.<br><br><div class="gmail_quote">

After doing some more digging, it appears this problem is not only<br>
related to temporal collections, but all XDMF/HDF5 files with spatial<br>
collections. If repeatedly open and close a file containing a spatial<br>
collection, Paraview's memory usage gradually increases until it hangs<br>
my machine. I observe this in both 3.6 and 3.8 RC2.<br>
<br>
Cheers,<br>
