Hi,
These are all good points. I also had severe issues with Antivirus - it
slowed down or prevented a lot of the network access. The IT services
had to add exceptions.
But you describe that it only happens after a couple of days of usage,
which is strange.
If you find out what the issues really is, please let us know, so we can
learn.

Hi Koos -
I had a talk with my wife Lene Fischer about your issues. (She is a
Assoc. Prof. teaching GIS at a department of the University of
Copenhagen using QGIS. I co-lecture with her on the use of spatial
enabled databases (PostgreSQL/ PostGIS)).
She hasn't experienced the issues you describe (but some other issues)
Here is some pointers:
* Use a long-term releases and keep up with the point releases
3.10.3 -> 3.10.4 (Which you do :-)
* Clean the temp dir regularly (Which you did :-)
* Check the setup of your windows pointers to user-dirs, temp space.
Sometimes they are not suited for computers outside the university
network (or inside, if the network sucks)
* Check if your logon name contains special characters outside
us-ASCII like accented character or blanks. QGIS is fine with
these but some add-on libraries is not. The logon name can be a
part of a path name that something chokes on.
* Check your antivirus by temporarily disable it before using QGIS.
* Check your disk space. The temp dir can "grow" considerably
during QGIS use.
* Check the amount of memory used on your computer. If you *are*
using all available ram you *will* get the symptoms you describe
* Install a minimum of plugins.
* Keep your windows installation as clean as possible. QGIS might
conflict with some other software installed on your computer. You
might try to install QGIS on computer with a new clean install of
windows. Check if the error is repeated on the new computer.
* You might try with installing QGIS from the "network installer"
utility instead of a stand-alone installation
(https://download.osgeo.org/osgeo4w/osgeo4w-setup-x86_64.exe). It
defaults to another installation directory than the stand-alone
installation. That might help.
* If nothing of the above works - try another version of QGIS i.e.
3.12.1.
The network installer has the possibility to install a "bleeding
edge" version of QGIS but I won't recommend using these in a
teaching situation (or any other situation which involves
inexperienced users). But you can use it in a testing situation

Hi Bo
Thanks for your quick response!
Sorry for the minimal information provided, I wasn’t sure what to add
(first question to the QGIS user list).
To answer your questions:
OS: Windows 10 – 64 bit
QGIS version: 3.10.4 64 bit, stand-alone installation
I’m not in any networked set-up, I’m working from home on my own
computer. I have only one plugin installed (QuickOSM), and I’ve
already tried uninstalling, but without any difference.
Since my question I’ve been trying some things, and I have deleted
the temporary QGIS files in my Local/Temp folder. When I open and use
QGIS now, I have the feeling it’s more stable again. It gives a hint
of freezing up at the start, but afterwards all goes quite well
again. Then again, not sure of this is a solid solution for fixing
this issue, as I have experienced this issue before completely
deleting and reinstalling everything QGIS-related on my laptop (using
REVO uninstaller). After this, QGIS worked fine for about a week
until today.
I do recall trying to load some large files into QGIS, maybe they
were stored in a temporary directory somewhere and deleting the
temporary files helped?
Anyways, it might be relevant for me to know. I’ve switched our
courses from ArcGIS to QGIS, and I’m really happy about it, but I
would like to be able to help my students if these kind of problems
occur.
Thank for the help already, not sure if there’s more to do for now,
but let me know if you have any more ideas.
Kind regards
Koos

3.10.4
Hi Koos:
That's not much information to go on.
What about: OS type and version ? 32/64 bit os ? QGIS version ?
QGIS 32/64 bit ? network environment ? Normal stand-alone
installation or Network installation ?
I'll hazard a *guess* based on my own painful experiences: You are
working in a networked windows setup, where your IT department has
made some modifications for home directory (including temp file
placement) and/or the userdata environment - maybe making it fully
dependant on the network. And maybe You are using the same login
account for all pupils. Combine this with a marginally functioning
network and it will be a train wreck
Another scenario: You have installed some plugin, that's not working
correctly.
What you can test:
* Disable/Remove all plugins from QGIS and test if the problem goes
away
* Load some GIS data locally on you computer and disconnect the
computer from the network. Then test QGIS again.
That said, QGIS ver. 3.10 onwards has long startup times. However
it's quick and stable after that

Dear all
I have a question regarding QGIS.
I’m using QGIS for my classes, but since a recent install my QGIS
keeps freezing right after startup. It doesn’t respond until
after a minute, then I can open some files and then it freezes
again. This keeps on going, making it impossible to keep working
with QGIS.
I’ve tried reinstalling, which always helps at first, but after a
couple of days it starts freezing again. I’ve also tried with
different versions, with the same result.
It might maybe have something to do with temporary files?
Has someone experienced the same issue, and are there possible
solutions that you know of?
Thanks!
Koos
