Alberto,
what a couple of other people on this list have already tried to tell 
you - without apparently triggering any reaction from you -  is that 
"too many processes" is not a very precise or helpful expression.
Too many compared to what ?  Compared to what you are expecting ? 
compared to the number of requests your server is supposed to process ? 
compared to the "maxThreads" attribute of the <Connector> element in 
your server.xml configuration file (maybe a hint here) ?

If you have many requests to process very fast, then maybe the number of 
processes (or probably threads) that you are seeing is normal and 
correct, and your server just does not have enough memory for what you 
are trying to do. Or maybe you need more servers.  Or maybe you just 
need a better application.

But you are not saying what you are trying to do, so it is hard to help you.

Maybe you would like to start again, describe your server (hardware, 
software, application) and what your problem really is ?
