Subject RE: java.lang.OutOfMemoryError
Date Thu, 05 Aug 2004 15:00:23 GMT
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 this 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 you app using the (now freeware and excellent) JProbe (www.quest.com)
and go from there.
