    <div class="moz-cite-prefix"><tt>Hi,<br>
        <br>
        Those messages say that OpenSIPS tried to open a TCP connection
        to a party which does not respond -&gt; there was a timeout for
        connect in 10 seconds. Because of this blocking in connects,
        there were not more opensips workers available to handle other
        traffic.<br>
        <br>
        So what you need to do is :<br>
        &nbsp;&nbsp;&nbsp; - minimize the impact of the blocking connect - see my
        previous email on reducing the connect timeout<br>
        &nbsp;&nbsp;&nbsp; - you may configure OpenSIPS not to open new TCP connect
        (but to reuse the existing ones, open by clients). See
        tcp_no_new_conn_bflag <br>
        &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;

        &nbsp;&nbsp;&nbsp; - try to understand the SIP patterns where such TCP connect
        fails so you can avoid them at script level.<br>
        <br>
        Regards,<br>
