    <tt>Hi, Mickael!<br>
      <br>
      Can you check if there are also any transactions hanged? Also,
      What is the scenario you are using? When are you populating these
      variables?<br>

        <div>I have some news.</div>
        <div><br>
        </div>
        <div>The suspects are not regular AVPs but branch AVPs that I
          set in a module.</div>
        <div><br>
        </div>
        <div>Is there a specific handling for those AVPs?</div>
        <div><br>
        </div>
        <div>Here is how I use it:</div>
        <div><br>
        </div>
        <div>static str bavp_msgops_flags =
          str_init("$bavp(_msgops_bflags)");<br>

        <div>pv_spec_t bavp_msgops_flags_spec;<br>
        </div>
        <div><br>
        </div>
        <div>In mod_init:</div>
        <div><br>
        </div>
        <div>
          <div>if (parse_store_bavp(&amp;bavp_msgops_flags,
            &amp;bavp_msgops_flags_spec)) {</div>
          <div>                LM_ERR("Fail to parse branch AVPs.\n");</div>
          <div>                return -1;</div>
          <div>}</div>
        </div>
        <div><br>
        </div>
        <div>In a command called from branch_route:</div>
        <div><br>
        </div>
        <div>
          <div>b_flags.flags = PV_VAL_INT|PV_TYPE_INT;</div>
          <div>b_flags.ri = 0;</div>
          <div>if(pv_set_value(msg, &amp;bavp_msgops_flags_spec,

          <div>            return -1;</div>
          <div>}</div>
        </div>

                              That's the correct usage, and the AVP is
                              attached to the transaction, and destroyed
                              when the transaction is destroyed.
                              However, it depends on the context when

                                                      Both maps are
                                                      relevant, because
                                                      both of them
                                                      contain id2name
                                                      mappings. So you
                                                      should definitely
                                                      look into the
                                                      avp_map too. Note
                                                      that those
                                                      mappings do not
                                                      store AVPs, they
                                                      only store the
                                                      real name of the
                                                      AVP, as you use in
                                                      script, and they
                                                      can be populated
                                                      at startup (in
                                                      this case they are
                                                      stored in PKG) and
                                                      runtime (stored in
                                                      SHM).<br>
                                                      It depends when
                                                      the AVP should be
                                                      destroyed: if they
                                                      are attached to
                                                      the transaction
                                                      (and they usually
                                                      are), they are
                                                      automatically
                                                      destroyed by the
                                                      tm module.
                                                      Otherwise the
                                                      module that uses
                                                      them, should take
                                                      care of that.<br>

                                                          only
                                                          avp_map_shm is
                                                          relevant since
                                                          the leak
                                                          appears in
                                                          shared memory.
                                                          I only see 4
                                                          elements in
                                                          this map while
                                                          I can see a
                                                          lot of
                                                          remaining AVPs
                                                          when looking
                                                          at the memory
                                                          dump created
                                                          at shutdown
                                                          using QM
                                                          debug.
                                                          Therefore, it
                                                          looks like
                                                          these AVPs are
                                                          not in the
                                                          map. Looking

                                                          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>
