We had memory loss with 5.0.19. We profiled a 5.0.19 web app and found that=
 memory was not being garbage collected too well. As soon as we upgraded th=
is went away and was proven by th profiling. Start by trying out 5.0.27 and=
 see how it goes. If it still happens then take Yoav's advice and profile y=
ou app using the (now freeware and excellent) JProbe (www.quest.com) and go=
 from there.
