[OpenSIPS-Users] multiple sub interfaces - opensips crashes

[Bogdan-Andrei Iancu]

Maybe we should consider (as future extension) the possibility to bundle 
multiple UDP listeners on the same worker.  In this case, we can have a 
large number of listeners with a relatively small number of workers/ 
processes.
