Thanks Gabriel,
I uploaded screenshots of a report created by the 'Memory Analysis Tool'
Eclipse plugin, in case that might help: http://imgur.com/a/Apt6K

Subject: Re: [Geoserver-users] Geoserver memory usage - possible GWC leak?
I will try with a profiling session later today.
@Justin: any advice on what kind of care should be taken to minimize
the proliferation of XSDSchemaImpl and GridCoverageReader instances?
Cheers,
Gabriel

Hello everyone, I've been monitoring memory usage of my geoserver instance
(2.1 snapshot, compiled about a month ago) running under tomcat. After 12-48
hours or so the PS Old Gen memory pool fills up completely . At this point
GC tends to consume much more CPU resources when it runs and barely makes a
dent in the PS Old Gen pool. Is this normal, or could there be a memory
leak?
I ran a memory analysis tool indicating most of it is made up of instances
of"org.eclipse.xsd.impl.XSDSchemaImpl" and
"org.geotools.gce.geotiff.GeoTiffReader" with the GWC Seeder thread as the
common originator of both.
I currently have the GWC disk quota usage monitor turned off
(GWC_DISKQUOTA_DISABLED = true). When turned on, the PS Old Gen Pool fills
up more quickly.
I have JAVA_OPTS set to: "-server -Xmx3072m -Xms2048m
-XX:CompileCommand=exclude,net/sf/saxon/event/ReceivingContentHandler.startElement
-XX:SoftRefLRUPolicyMSPerMB=3600 -XX:+UseParallelOldGC -XX:NewRatio=2
-XX:PermSize=256m -XX:MaxPermSize=512m -XX:+UseCompressedOops"
