    <tt>Hi, Mickael!<br>
      <br>
      This is not entirely true - you can define AVPs with the integer
      value 0. Those will have avp-&gt;flags == 0 and avp-&gt;data == 0.<br>
      What I'd do, is to note down the avp-&gt;id value of those AVPs
      and then try to see their names. To do that, you'd have to look
      into the avp_map and avp_map_shm maps to see the corresponding
      name for that id. Alternatively you can call in your script the
      avp_print() method, which prints all the AVPs for a specific
      transaction along with their id and names. Let me know how this
      goes.<br>
      <br>
      Best regards,</tt>

                        <div>I took a core dump of the attendant

                        <div>In this list of fragments, I can see a lot

                        <div>I see some AVPs without data (avp-&gt;data
                          == NULL, avp-&gt;flags == 0). But something is
                          weird, it looks like that all AVPs that don't
                          have data have the same id. It looks like
                          duplicate AVPs (in different memory

                        <div>Some AVPs do have data and have a format

                        <div><br>
                        </div>
                        <div>Some AVPs looks corrupted. For example, I
                          found an AVP with same ID as the AVPs without
