klaus,
thanks for the pointer. i pulled out shell script from it (below).
it would be still nice to know how kamailio is dispatching the requests
to worker processes.
for udp, is the kernel that decides which process reads the datagram.
For tcp, iirc, the main tcp process dispatches connections to tcp
workers on the least loaded (by number of connections) mode.
Cheers,
Daniel
