<p>Hi,</p>
<p>its not the item in the layer properities. Its the labeling feature <strong>ABC</strong> shown in the attached pic 2.</p>

<ul></ul><p>Hello,</p>
<p>thanks for your explanations... This new labeling plugin is experimental (as the new symbology system).</p>
<p>I am still not able to reproduce the bug with the 1.5.0 trunk (under GNU/Linux Debian). I can "zoom" to 1:3 (and even 1:1) without crash.</p>
<p>Perhaps is it MS Windows specific ?</p>
<p>What if you try to set the scale with the zoom-in tool (focus on the label and try to zoom in progressively until 1:3 or less) ?</p>
<p>Perhaps the bug is related to free labeling placement only... (It crashes a lot with this mode) ?</p> QGIS Application - Bug report #2872: Crash using the new labelling engine at very high scaleshttps://issues.qgis.org/issues/2872?journal_id=226162010-07-21T09:45:39ZGerhard Spieles
<ul></ul><p>Hello,</p>
<p>in a new project with only the layer, i wish to label, all is ok and I can zoom 1:1, 2:1 ....<br />Adding more layer to the project and zomm in, then Qgis crash.<br />I@m not competent enough to localize the problem, but it seems, that the labeling feature has a memory leage/problem, when data gows up.</p>

<p>can you post a sample of the data that is causing the crash?</p> QGIS Application - Bug report #2872: Crash using the new labelling engine at very high scaleshttps://issues.qgis.org/issues/2872?journal_id=226182010-07-22T12:14:21ZGerhard Spieles

<ul></ul><p>Hi,</p>
<p>no crash at any scale level with the labelling plugin active. I'm under ubuntu 10.04 with qgis 1.5. Can you test this under a different platform?</p> QGIS Application - Bug report #2872: Crash using the new labelling engine at very high scaleshttps://issues.qgis.org/issues/2872?journal_id=226202010-07-23T06:36:10ZGerhard Spieles
<ul></ul><p>Hello,<br />tested it on win vista 32bit and qgis crash also.<br />Programms behavior iS: with every zoom in, the programm needs more time to display the map until qgis crash near scale 1:3.<br />Gerhard</p> QGIS Application - Bug report #2872: Crash using the new labelling engine at very high scaleshttps://issues.qgis.org/issues/2872?journal_id=226212010-07-24T10:45:05ZGiovanni Manghigiovanni.manghi@gmail.com
<ul></ul><p>Hi,</p>
<p>I tested your vectors with the new labelling engine under qgis 1.5/osgeo4w in Windows Seven and I cannot replicate the crash.</p> QGIS Application - Bug report #2872: Crash using the new labelling engine at very high scaleshttps://issues.qgis.org/issues/2872?journal_id=226222010-07-25T09:11:46ZGerhard Spieles
<ul></ul><p>Hell0,</p>
<p>I@ve just tested it on a new build win7 machine and qgis crashed (see attachment)</p> QGIS Application - Bug report #2872: Crash using the new labelling engine at very high scaleshttps://issues.qgis.org/issues/2872?journal_id=226232010-07-25T09:23:23ZGiovanni Manghigiovanni.manghi@gmail.com
<ul></ul><p>can you please test QGIS in english (en_us)? it is the only difference I'm seeing.</p> QGIS Application - Bug report #2872: Crash using the new labelling engine at very high scaleshttps://issues.qgis.org/issues/2872?journal_id=226242010-07-25T09:29:16ZGiovanni Manghigiovanni.manghi@gmail.com

<p>I tested myself and no crash.</p>
<p>In the labelling plugin, what configurations are you using?</p> QGIS Application - Bug report #2872: Crash using the new labelling engine at very high scaleshttps://issues.qgis.org/issues/2872?journal_id=226252010-07-25T09:37:16ZGiovanni Manghigiovanni.manghi@gmail.com
<ul></ul><p>ok got it.</p>
<p>There are configurations in the plugin that as a fact make qgis eat memory and then crash as described in this ticket.</p>
<p>Just use one of the attached vectors and then choose for example "using perimiter". A scales around 1:1 it starts eating memory and then crash. Maybe this happens with other configurations. It does not crash with the default one, "around centroid".</p> QGIS Application - Bug report #2872: Crash using the new labelling engine at very high scaleshttps://issues.qgis.org/issues/2872?journal_id=226262010-07-25T09:46:12ZGerhard Spieles
<ul></ul><p>Hi,<br />picture with labeling configuration is attached</p> QGIS Application - Bug report #2872: Crash using the new labelling engine at very high scaleshttps://issues.qgis.org/issues/2872?journal_id=269462011-12-16T08:51:32ZPaolo Cavallinicavallini@faunalia.it

It is confirmed on 1.7.3 that at very high scales, when the new labelling engine is used, QGIS starts eating memory, take a lot to render features and labels and ultimately freezes/crashes. This at least happens under Windows/osgeo4w BUT on master it works ok.</p>
<p>The attached project is good to make tests and replicate the issue.</p>
<p>I'll close this as fixed, but probably would be better to try backport the fix for the 1.7.x versions.</p>
