We have over 4 proxies running openser-1.1.0-notls. Recently we started to see the following error in the logs of one of the proxies:<br><br>Feb 4 06:46:21 proxy01 /usr/local/sbin/openser[4670]: ERROR: udp_send: sendto(sock,0xb3c35898,594,0,0xb3c257f4,16): Invalid argument(22)
<br>Feb 4 06:46:21 proxy01 /usr/local/sbin/openser[4670]: CRITICAL: invalid sendtoparameters one possible reason is the server is bound to localhost and attempts to send to the net<br>Feb 4 06:46:21 proxy01 /usr/local/sbin/openser[4670]: msg_send: ERROR: udp_send failed
<br>Feb 4 06:46:21 proxy01 /usr/local/sbin/openser[4670]: ERROR:tm:t_forward_nonack: sending request failed<br><br>Now the errors suggests a binding to localhost, however our openser.cfg has the following:<br><br>listen=eth0:5060
<br><br>After a brief search we came across a couple of over people having a similar problem. Once of the suggested fixes was to add a mhomed=1 line to the cfg.<br><br>Well we tried this (even though we are not multi homed) and the error changed to:
