I am sending topic messages continuously and with RC2 memory usage is stable at around 60MB. When I switch to the release version (no change to user code) it uses far more memory; after 15 minutes it uses approximately 150MB but does seem to remain stable at this level. I am just using task manager to look at the process. If anyone can recommend an (open source) memory analyser I would be happy to investigate in more detail where the leak is.
