Hi, it is not very easy to "guess" a memory leak. Of course upgrading to the latest Resin (3.0.21) could help. But you should better consider profiling your application with e.g. JProfiler. You can download an evaluation version which is valid for 10 days. If you are using JDK 1.5, using jconsole http://java.sun.com/developer/technicalArticles/J2SE/jconsole.html could also help. You could at least find out which memory spaces are involved in the memory leak.
