----------------------------------

Hi, 

We noticed that the heap usage for RHQ/JON shot up by like 400MB after 11 users logged into the (JSF/RichFaces/Seam-based) GUI. I took a heap dump and saw that most of this memory was being consumed by hefty org.ajax4jsf.util.LRUMaps inside org.ajax4jsf.application.AjaxStateHolders inside Tomcat Sessions. Googling brought me to this JIRA issue. I tried the workaround described in the forum post associated with this issue (setting the com.sun.faces.numberOfViewsInSession and com.sun.faces.numberOfLogicalViews web.xml context params to 1), but, based on our tests, that did not lower the heap usage at all. JON is using RF 3.3.0.GA, which is the version of RF this issue was reportedly fixed in. What was the fix exactly? Was it related to the getNumberOfViews() method Brian Kates mentions above? Is there some other RF web.xml param we need to set to enable the fix?

Thanks,
Ian

> AjaxStateHolder saves all views in the session. But the same view can occur several times in this "cache"; the views from this "cache" are not reused and just fill the session. If an application has many large views and deals with many concurrent sessions, the heap can easily grow up to Gigabytes(!)
