Hi Seth,
layer has an EXTEND (ensured this after reading the results of a search
through this mailing list).
I also did a mapserver 8 setup with a postgis layer and the same layer
definition on my private laptop
also with a postgis source and it works flawless. - but it uses IIS as
webserver.
I wrote, that according to logging the data comes back from the
postgreSQL source and when i do
comment out the CLUSTER the data is correctly displayed.
But, i will try to test your idea about the shapefile source, will come
back then.
thanks anyway and BR
Stefan

Hi,
A couple of things to try to narrow down the issue:
1. If you are able to export the PostGIS layer to a shapefile, then you can
change the DATA of the layer and see if there is still a crash.
2. Is there an EXTENT set on the layer? I ran into an issue using MS SQL [1]
and clustering. Try adding one manually.

Hi There,
in our application we're upgrading our v7.6 MapServer to v8.01.
Everything seems to work good so far but we have one layer that uses
Clustering of points
and whenever this layer should be displayed MapServer 8 crashes
reproducably.
This layer works flawless in v7.6 and clustering is setup exactly from
the book.
When i comment clustering out, the layer is displayed, so all other
style features do work.
Datasource is a PostGIS layer, webserver is Apache 2.4.59.
Looking at the debug output, the data comes back as expected from the
database,
even clustering is logged and no error in the MapServer-Logfile.
The crash is reported in Windows Application-Eventlog with only cryptic
reasons that do
not really result in any valid answers when googling.
..there is a word "StackHash" included that might point to DEP
(DataExecutionPrevention)
of Windows, - but since all other layers do work with the MapServer-Exe
it would be hard
to understand why windows does prevent the output of clustered layers.
We're using Windows Server 2022 21H2 Datacenter Edition, 8 CPU 32GB RAM.
Anyone heard of this crude behaviour, I'm running out of ideas?
Thanks in advance for any hint
