    Hi Oleg,<br>
    <br>
    OK, I see that slowly there is a progress on that timer task. Based
    on the numbers, I see a ~40sec overrun for the timer task. How often
    do you send the OPTIONS pings in dispatcher?<br>
    <br>
    Regards,<br>

                                        <br>
                                        The "ds-pinger" is the
                                        dispatcher's task for generating
                                        the probing pings to the
                                        destinations. And it seems it
                                        takes a lot of time to this task
                                        to do its job (and it has
                                        nothing to do with the traffic
                                        you have on your opensips).<br>
                                        <br>
                                        So, the destinations in
                                        dispatcher:<br>
                                        - how many they are ?<br>
                                        - are they defined as FQDN or
                                        IPs ?<br>
                                        - are they via UDP or TCP/TLS ?<br>
                                        <br>
