hmm, invalid argurment ... try with this line:

LM_ERR("can't send command to a RTP proxy (%s/%d) [sock %d (%d), vcnt
%d]\n",
strerror(errno), errno, rtpp_socks[node->idx], node->idx, vcnt);

maybe will give some hints about which value is invalid.

Can you try as well with an unix file socket:

modparam("nathelper", "rtpproxy_sock", "unix:/tmp/rtpproxy.sock")

then start rtpproxy with -s unix:/tmp/rtpproxy.sock

I have no solaris (sparc) to try myself...

Cheers,
Daniel
