I become crazy to realize a serial forking.
I try to use load_contacts() and next_contscts().

This is my openser.cfg nd my location table:
In teory when I call [EMAIL PROTECTED] the location with the q value equal to 0.80 it is the first but it is processed only the location
[EMAIL PROTECTED]

Help!!!
