[Geoserver-users] GeoServer 2.21 - Cascaded WMS returns Connection reset

Mattias_Andren · December 16, 2022, 1:28pm

Hello everyone,

I have a problem with Cascaded WMS’s on GeoServer 2.21.

Some layers frequently report the error ‘Connection reset’ while some layers works fine.

This problem does not occur in a previous version 2.17.1 (using the same geoserver_data directory).

I have tested the latest version 2.22.0 with the same result.

My environment is:

Windows Server 2016 Standard
Java: Eclipse Adoptium JRE 11.0.15.10 hotspot
Tomcat 9.0.65
GeoServer 2.21

Some Questions:

Is this a known problem?
Is there a way of increasing the logging in this area of GeoServer to see if the problem is in GeoServer or in the remote WMS server?
Any suggestions on how I can investigate this problem further?

Best Regards

Mattias Andrén

Mattias:

There is a way to increase the logging, see instruction here: https://docs.geoserver.org/stable/en/user/configuration/logging.html

Quickly the idea would be to make a custom logging configuration (copy one of the existing ones into a new file), and add some lines to log wms client interaction…

So the instructions have this example:

GeoTools Logger names match up with the package names in the project javadocs overview.
As an example package org.geotools.data.shapefile is listed, allowing level of shapefile logging to be controlled:

So I think you could use “org.geotools.ows.wms”:

Let us know what you find?

Thanks!

I tried increasing the logging as you suggested below, and It works.

I can now see the requests that are made.

I do not get any more information why the request is failing though.

If you make the requests you see logged yourself (using a browser or cURL) … do they work?

Other options:

are you comfortable with wireshark or similar to watch the two programs talk to each other?
is some kind of firewall watching and closing down connections?

You indicate you are upgrading from 2.17.1 … we did provide the option of using a different HTTP client in the GeoTools Java library used for WMS access.
I am not sure how you configure that from GeoServer (there should be a choice between the built-in java URL and HTTP connections, and the Apache HTTP library).

Andrea_Aime4 · December 20, 2022, 9:36am

I was about to suggest the same. The default is with the Apache HTTP library with a connection pool and persistent connections,
which is faster but less reliable. The alternative is to turn that off, creating a new HTTP connection for each request.

To do so, un-check the “HTTP connection pooling” option:

Thanks for the suggested workaround!

I have unchecked the “HTTP connection pooling” option as suggested below and do not get the “Connection reset” error any more.

I occasionally get a “read timeout” error, but not even close so many as before.

Is the performance affected when the “HTTP connection pooling” is unchecked?

Best Regards
