Thank you for your response!

However, I was slightly unclear. Sorry. The connections are in the 
ESTABLISHED state. I called them inactive because since there were so 
many of them I just assumed clients were pre-connecting and waiting (in 
what I called an inactive state) for some time before sending the real 

Now that I think about it, clients shouldn't be doing that as that would 
be pretty rude :-) So I think I need to add some JMX monitoring code and 
figure out what my traffic patterns / connection rates are before I 
bother anyone about this. Sorry for the noise.
