Have you tested with either the latest 2.14 nightly or master
nightly?<br>
An issue with OGR connection pooling has been resolved recently. And
I wonder if that could be related.<br>

<div>Hi again,<br>
<br>
</div>
I also forgot to mention that I have no memory leak when
using the same dataset in PostGIS ( tested by importing
the Shapefile in PostGIS with shape2pgsql )<br>

<div>I forgot to mention the steps to
reproduce the bug, and the precautions
to take :<br>
<br>
</div>
* open the project in QGIS 2.14 ( I have
not tested with older versions)<br>
</div>
<br>
* open a terminal and use this kind of
command to monitor QGIS memory consumption :
htop, or ps with<br>
watch -n1 'ps -aux --sort -pmem | head -5'<br>
<br>
</div>
* Navigate through the project by zooming in
and out, pan, etc. I think you emphasize the
memory leak by displaying the layer at small
scale ( with many buildings displayed)<br>
<br>
</div>
<div>* Be aware that this will increase the
memory, so keep an eye on the memory
consumption so that your system has enough
free memory to work properly.<br>

<div>Hi devs,<br>
<br>
</div>
I have just found a memory leak
in QGIS Desktop (and server)
with the project available in
[1] ( a 20Mo tar.bz2 )<br>
<br>
</div>
This is a very simple project with
only one buildings Shapefile ( SHP
68Mo). This layer has been
exported from PostGIS from a query
wich aimed to simplify the
building for fast rendering. <br>
<br>
The geometries have been
simplified ( I used SnapToGrid,
then (St_Dump(St_Union(a.geom)))
to remove as many nodes as
possible )<br>
<br>
</div>
The layers has ~ 700 000 features.<br>
<br>
</div>
Has anyone encoutered such a leak ? <br>
<div>
<div>
