[SR-Users] udp_send "Invalid argument"

[Juha Heinanen]

in some of my tests i get the following udp send related errors, when
request is t_relayed:

Oct 24 11:20:20 test /usr/sbin/sip-proxy[10032]: INFO: Routing initial

$du is set to sip:+35892223333 at 193.166.3.2;transport=udp and the proxy
is listening on many sockets, both 127.0.0.1 and external ip address.

any idea what might cause the errors?
