[Geoserver-users] Geoserver keeps saying 'your session timed out'

I’ve posted in Codehaus but not sure if it went through to the maillist, so posting again…….

I have been using GeoServer for a simple private OpenLayers app. The geoserver is installed in the default Java environment, not on any additional server container. Several days ago when I tried to use many features through the geoserver web interface, it started to return this following error:

Sorry, your session timed out…
It looks like you waited too long to make that last change.if this continues to happen, you should get in touch with your system administrator.
Go back to the home page and try again.

This has been going for several days. I’ve restarted everything. I Also checked the log, where there is no ERROR, but a lot of WARN. The following are several examples of warns:

2014-05-20 00:30:07,391 WARN [geoserver.web] - Unable to find property: ‘format.wms.kmz’ for component: [class=org.geoserver.web.demo.MapPreviewPage]

I searched online and found many suggesting that this issue is due to the lack of Permgen Space. I’ve tried to set: [-Xmx512m -Xms48m -XX:MaxPermSize=512m] in the …\geoserver\bin\startup.bat. But it didn’t work.

Many articles provide solutions for making such settings for TOMCAT, but my geoserver is not running on TOMCAT so what else can I do? Any help would be appreciated!

Thanks!
