  No.  If you have not set src_ipaddr before, then it adding it now won't change things.

  I suspect that one of your home servers is down.  Limitations in RADIUS mean that the server can only send 256 packets on one socket before it needs to open a new socket.  So if a home server is down or slow, it might very well use 256 packets & 256 sockets, just to talk to one home server.

  You may have to edit src/lib/packet.c as I suggested before.  But even that may not help if one of the home servers is down.
