    <p>Hello,</p>
    <p>if it is a runtime issue, then it is better to upgrade to a
      supported release series and try to reproduce it.</p>
    <p>Looking at startup/shutdown code is easier than the rest used
      during runtime by a module, but it is not the case here. So we may
      waste a lot of time to dig into it and discover it was fixed or
      the code in an older release was refactored not matching any
      longer what is now in stable releases.</p>
    <p>Cheers,<br>
      Daniel<br>

        <div>The problem does not just occur when kamailio is restarted.
          The restart was the way I found to reproduce the problem,
          because when a proxy is restarted, there is more traffic from
          DMQ messages, so the problem is more likely to occur.<br>

            <p>Hello,</p>
            <p>does it happen only when doing restart of kamailio? Can
              you send the full backtrace from gdb?</p>
            <p>Also, 5.0.x is no longer a supported release for quite
              some time, try to upgrade to 5.2.x or even better to the
              latest one 5.3.x and see if you can reproduce it with one
