    <p>Hello,</p>
    <p>can you install the package with kamailio debugging symbols? Then
      take again the kamctl trap with two async workers, it should
      contain more details about what pieces of code run.<br>
    </p>
    <p>The package should be named like kamailio-dbg...</p>
    <p>Besides that, can you also do a 'top' and see what kamailio
      processes (their PIDs) eat a lot of cpu?</p>
    <p>Cheers,<br>
      Daniel<br>

            <p>Hello,</p>
            <p>if you can, it would be interesting to get the backtrace
              and see what was causing the load.</p>
            <p>Iirc, the Async Task Worker should wait on read on an
              internal socket, so it should be no CPU used when nothing

                        I'm running Kamailio version 5.3.3 on a CentOS
                        6. I started noticing that "load average" value
                        increases rapidly with the start of Kamailio:
                        <blockquote style="margin:0px 0px 0px 40px;border:none;padding:0px">
                          <div># uptime</div>
                          <div>17:47:52 up 4 days, 17:47,  3 users,
                             load average: 7.02, 7.01, 6.02</div>
                          <div><br>
                          </div>
                        </blockquote>
                        It will start to decrease immediately after
                        Kamailio is stopped.
                        <div><br>
                        </div>
                        <div>Does anyone know what could cause this and
