Hi All, I have a web application which is in production and uses the following technologies : EJB 3.0 Hibernate Seam JSF Facelets Ajax4JSF MySQL 5.0 I am using JDK 1.5.0_09 I have around 73 SFSB which are not using conversations and 78 SLSB and 43 Business objects. In production, there are four users which are connected simultaneously. The HTTP and EJB Session timeout is set to 4 hours ..... However, the server has to be restarted at least twice a day due to OUT OF MEMORY leaks associated to Permgen space ..... I was getting this problem during development previously but increasing the permgen space to 256M solved this issue ... I am not sure that implementing conversations only would solve my problems .... Can anyone have other suggestions on what could be wrong. This is really posing a huge problem for me Cheers, Jankee Yogesh Software Developer M-ITC LTD View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4039694#...
