        <div><br>
        </div>
        <div>You were right, found out the problem was a customization
          we did in a module. </div>
        <div>Didn't know that get_dlg_by_ids function adds a ref
          internally so the dialog is never released. The problem is
          that this customization is not called on every call, so leak
          didn't happen very often. Now we are calling dlg_unref
          properly.</div>

              The dump shows you have ~29K dialogs in memory....maybe
              your billing module is messing up with the dialogs?<br>
