Hello,
My opensips receive a lot of a same messages.
I try to fix this with follow part of script.
Why not working?
if (is_method("MESSAGE")) {
     if ( $avp(receive_message) == $ci ) {
	xlog("L_ERR",	"I receive already this MESSAGE");
	exit;
     }
     $avp(receive_message) = $ci;
      .............................
}
