hi,

I am running JBoss AS 5.1 with some web applications. I run jboss using following jvm config:




After start my java.exe process occupies aroudn 2GB of ram. After few hours it's becoming 4,7GB and is almost inaccessible...

I tried YourKit profiler, Eclipse Memory Analyzer with dump from jmap. Nothing, when my jboss java.exe process was 3,5GB, the analyze shown 2 possible memory leaks:

- 10 instances of org.apache.catalina.session.StandardManager, loaded by org.jboss.classloader.spi.base.BaseClassLoader @ 0xa9070438 occupy 276,022,464 (16.18%) bytes.

- 701 instances of org.jboss.virtual.plugins.context.zip.ZipEntryContext, loaded by org.jboss.bootstrap.NoAnnotationURLClassLoader @ 0x9fff7dc0 occupy 221,926,760 (13.01%) bytes.

This actually tells me nothing.

However YourKit shows 7500 instances of EDU.oswego.cs.dl.util.concurrent.WriterPreferenceReadWriteLock

I'm stuck and don't know what to try next. Anybody has an idea?
