Hi,

Please give a bit more details. Imagine that you are somebody who do not know 
your data and queries and think what information you would need for setting up 
a same kind of environment and for making same kind of queries to show the 
issue.

Aihe: [Geoserver-users] WFS issue when query several types at the same time

Hi all,

I would like to use WFS on my geoserver instance in order to make queries with 
several feature types in the same query (from OL based application), in order 
to manage cluster of features on the client side even if the feature type is 
different.

When I try to do so, GEOSERVER is busy for a very long time and I finished with 
a java.lang.OutOfMemoryError : GC overhead limit exceeded.

If I try to query each feature type separately, I have no issue at all.

I run the 2.16.0 version on a Linux VM (RHEL 7.3) on Tomcat 9, with Java Oracle 
1.8. The server has 2 CPU and 8 Gb of memory. Java is configured to start with 
Garbage Collection and 2 Gb of memory.

The data comes from a Postgis database hosted on another server. The layers for 
the feature types are defined with SQL views in Geoserver.

What should I do to solve this problem ? Or is there another/better solution to 
meet my requirement (being able to do cluster of features client side with OL, 
with feature of different types).

Regards
