Hi, > Using MessAdmin, I noticed that the size of the attribute > 'org.apache.myfaces.application.jsp.JspStateManagerImpl.SERIALIZED_VIEW' in > session is continualy increasing. Approximately 100K by viewed page.
yes; With the web.xml setting org.apache.myfaces.NUMBER_OF_VIEWS_IN_SESSION you can influence the amount of stored views in the session in order to restore them when navigating with the back button. However, the JspStateManagerImpl holds *all* the views in the session - regardless the setting - but with a weak reference. Means it will be freed out of the memory if gc determines that memory consumption is high. Because of this, the tool recognizes increasing memory consumption. cheers, Gerald -- http://www.irian.at Your JSF powerhouse - JSF Consulting, Development and Courses in English and German Professional Support for Apache MyFaces
