[Geoserver-users] GeoServer web-interface hangs (seemingly randomly)

[Aleksander V. <ale...@ne...>]

Hi list,
We've been having trouble with GeoServer for a while, and the problem does not seem to go away.
There have been two (non-related? or are they related?) problems.
The first is where the web-interface stops working at times (the loading just hangs), and the second is where a WMS request hangs?
There could be a network or tomcat issue, but it seems to just happen with GeoServer, we're running other services just fine. 
We're running GeoServer version 2.4.4 on tomcat 7.0.50. We're using one PostGIS datastore and two Shapefile datastores (99.9% of the requests are to the PostGIS datastore).
The WMS request that hangs is usually (perhaps always) to a published feature type with point data (EPSG:4326) and has around 70k points stored. This only happens if the request has not been sent for a while (if it's not stored in cache?). If the request is re-sendt instantly, it gets loaded instantly, or else we could wait and it might load after some minutes. Is it my configuration that could be wrong? An example of request is: /wms?LAYERS=layerName&FORMAT=image%2Fpng&TRANSPARENT=TRUE&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&SRS=EPSG%3A4326&BBOX=-83.238653735919,6.761346264081,13.522692528162,103.52269252816&WIDTH=256&HEIGHT=256
Here is a short extraction of server-status in tomcat for when the web-interface stops working (or, it "works" but it hangs and loads after perhaps 15+ minutes): http://pastebin.com/CDTM6w5d As you can see, the stage halts at S, which is service. This might start when I enter the "layers" list at web/?wicket:bookmarkablePage=:org.geoserver.web.data.layer.LayerPage or the org.geoserver.web.data.resource.ResourceConfigurationPage - but it only happens sometimes and I can not confirm that the reason is entering one of these pages. This does not affect WMS/WFS queries, but all web-queries it seems.
Thanks for any help that could solve these problems. And I'd be happy to give more information if there is anything in particular that could help solve the issue.
Cheers,Aleksander Vines
