I have tried removing the method call to getNextTeaserRecipes() from pages.xml and the problem is still the same. The only solution is still setting the session timeout to 2 minutes. I discovered that the growth rate of number of instances is higher with a longer session timeout, like between 10-30 minutes but for a lower number like 5 minutes the growth rate is much lower and for 2 minutes it is 0 i.e. no growth rate. Please help me! Is something wrong with my code or is it a bug in seam or ejb3 or what do you think? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4115598#...
