[Geoserver-users] GeoServer stalling/freezing until further prompted

Hello all,

I have set up a GeoServer for the small company I work for and have been
learning along the way. A summary of our current operation is we serve up
TIF file layers using WMS through a) OpenLayers (through a URL) and b) QGIS
(importing as WMS layer).

We have had an issue which crops up mostly when trying to connect to the WMS
service through QGIS, but has also occurred when trying to load an
OpenLayers link. The GeoServer console will seemingly freeze and nothing new
will be outputted regarding the action. The application (OpenLayers or QGIS)
will either become temporarily unresponsive or just sit there loading, until
another request is made (usually by loading another OpenLayers layer). The
frozen application will then either resume as normal or fail the action, so
it's almost like the second request boots GeoServer back into action.

I have tried using logs to diagnose the issue (connecting to WMS through
QGIS until it freezes, then attempting to fix by loading a layer through
OpenLayers) and have found that the problem isn't reported when the
connection fails, and when it does succeed the following is outputted (which
seems to be just standard logging, no error):

2018-11-21 13:03:22,589 INFO [geoserver.wms] -
Request: getServiceInfo
2018-11-21 13:03:22,605 INFO [geoserver.wms] -
Request: getCapabilities
  Namespace = null
  UpdateSequence = null
  Version = 1.1.1
  Request = GetCapabilities
  BaseUrl = http://xx.xx.xx.xx:xx/geoserver/
  Get = false
  RawKvp = {REQUEST=GetCapabilities, VERSION=1.1.1, SERVICE=WMS}
  RequestCharset = null

I've tried extensive googling and can't seem to find anyone who's had a
similar issue. Is anyone able to recommend further debugging steps or has
had a similar issue before?

Setup info: GeoServer 2.13.1 running on Java 1.8.0_161-b12 64 bits, running
on Windows Server 2012 R2 Standard

Cheers
Sam

Hi,
this issue is unusual, does not ring a bell (did not see it before).
If you get no errors in the GeoServer logs, it’s likely that GeoServer has seen no issue.
I see you’re on Windows, wondering if it might be related to some firewall configuration instead?
Generally speaking, I’d look in potential network related issues (either hardware or software ones).

Cheers
Andrea
