Re: [Qgis-user] Qgis crashes while loading WMTS layers

[Jonathan Moules]

Hi Patrick,

I'd suggest reporting this to the QGIS bug tracker as a regression.

Cheers,

Jonathan

Further investigation and comment

Since recently installing Qgis 3.4.15 or 3.4.14 on some of my 
computers running Debian 10, I immediately began to see a trend of the 
software exhibiting an increased tendency to crash when working with 
certain WMTS layers that I had previously worked with extensively over 
recent weeks for mapping purposes.


After attempting numerous changes including special versions of 
projects containing no file based raster layers and only containing 
one WMTS layer at a time and being unable to use the software 
regardless I created a virtual machine running Debian 9 which has the 
latest version available for that platform, 3.4.4. This has resulted 
in immediate major improvement in the reliability of the software to 
the point I can resume using it without the numerous crashes of the 
software that have been noted recently, especially in the last week 
approximately.

Good day to all.

Not so long ago I wrote a post about issues handling large numbers of 
raster files. This results from what appears to be an architectural 
design limitation of Qgis in that it only has enough resources 
available for a certain (unknown) number of raster layers and does 
not have any effective system for dealing with the exhaustion of 
these resources.


I also noted that the software does not appear to have the ability to 
use the swap (virtual memory) resources within a system to deal with 
the apparent exhaustion of resources, as other software would. For 
example, Gimp which I use for graphical editing is able to handle 
certain projects using a swap space of 200 GB, which consists of 32 
GB of physical RAM and the rest in SSD. It is not unusual with some 
of these graphics projects to have 100 GB or more of swap space in 
use, without crashing the system. (This being possible since Gimp 
2.10 with its ability to write files of more than 4 GB)


Whilst it is possible to manage the number of layers with file based 
rasters, this cannot be done with a WMTS server because there is no 
way I am aware of to manage the number of layers that can be 
downloaded from the server.


Version 2.18 and earlier almost never crashed with excess layers, 
usually all that would happen is a layer would be displayed with 
invalid data. However, crashes have become the norm with 3.x versions 
of software.


It seems to me there is a big architectural problem in the software 
with its inability to utilise the full resources of the system in 
order to process the number of layers that a WMTS server is capable 
of issuing.

Can anyone please give a link to the plugin? Perhaps we can find an alternative.

Re: [Qgis-user] Plugin Slicer

[Paolo Cavallini]

Hi Everton,
please note that raster reclassification can be achieved with a variety
of other methods, several in QGIS Processing. Alternatively, you can
contact the original author and ask whether he has any plan to upgrade
it. Of course some support from your side will increase the chances that
this will happen.
I do not recommend downgrading, as QGIS 2 is officially end of life, and
no longer receives support.
Cheers.

Re: [Qgis-user] Plugin Slicer

[Christine]

dear Everton,

checked the plugins in my *QGIS 3.10* installations and may confirm, that a
SLICER plugin is not available via the plugin manager.  Found also  
https://plugins.qgis.org/plugins/Slicer/
in the QGIS Plugin repository,
telling explicitly that the SLICER plugin was created for QGIS version 2. 

So it seems you have to *install a QGIS verson 2* if you want to use the
SLICER plugin. 
Principally it is possible to have several versions of QGIS installed on the
same machine. But I have actually experienced problems with the
geoprocessing of QGIS 2 after having installed also QGIS 3. May somebody
else give an advice for that ?
