Hello
Many thanks for the suggestion.
I downloaded the log and tried to examine it.
I do read the word "ERROR" in connection with the conclusion of the WFS
request for the shapefile "sottocategorie_ag".
I do not see the beginning of the request.
I suppose the last line documents the initial request.
The ERROR says:
"2015-08-11 05:30:32,567 ERROR [geoserver.ows] -
java.lang.OutOfMemoryError: Java heap space"
Can this be due to "invalid geometries"?
The Geoserver is running on a PVS (Digital Ocean Droplet) with 512 MB
Ah, this might be the cause. How did you install/deploy GeoServer?
It might be running with just 64MB of memory on such a small machine
(Java server side ergononomics not kicking in, and as result, the JVM
running as if it was working on an applet).
We should ensure that it runs with at least 256MB in that environment, but
to
do so, we need to know how you deployed it.
memory. Is this cause of the error? Is the software not able to forecast
that heap will need more space than what is available in order to manage
the situation? Such a problem can occur with any memory dimension or is
there a minimum memory requirement in order to avoid it?
We normally recommend to run GeoServer with 2GB of heap, on a machine that
has at least 4GB
of memory, it's possible to run it with less of course, but it will
severely limit the amount of
concurrent requests one can handle.
Your WFS download can be going OOM because of many reasons, large geometries
being one, concurrent requests being another (and if you're running
GeoServer with
just 64m of memory, well, we should be thankful it started at all)
Cheers
