Thanks for your reply.
I already thought about that but I'll have other problems if I do so:
- I need some variables to be common between the instances (Maybe it's
not so difficult with RPC or a DB or shared memory).
- I also need to keep a pool of all the outgoing the connections (to
perform some real time stats and to limit the number of connection per
But if I do not have other choices, it's certainly what I'll have to do...
