First, start with using a profiler to ensure that your application

My problem is that everytime the context is reloaded, "top" shows a memory
usage increase with about 2Mb, until tomcat runs out of memory.

My long-running Tomcat processes become huge. I have the max heap set
to -Xmx512m, yet after a day or so the virtual size of java reaches
