<tt>Hi, Mickael!<br>
<br>
This is not entirely true - you can define AVPs with the integer
value 0. Those will have avp->flags == 0 and avp->data == 0.<br>
What I'd do, is to note down the avp->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,<br>

<div>When I said I found AVPs without data, I may be
wrong. avp->flags == 0 probably means the AVP data is
an integer. So, that explains the weird values (e.g.
0x8000) I tried to interpret as memory addresses.</div>

<div><br>
</div>
<div>Here is what I've done.</div>
<div><br>
</div>
<div>I took a core dump of the attendant
process. Then, I stopped OpenSIPS so that it
frees allocated fragments, and at the end
lists all fragments that are still allocated.</div>
<div><br>
</div>
<div>In this list of fragments, I can see a lot
of AVPs.</div>
<div><br>
</div>
<div>I see some AVPs without data (avp->data
== NULL, avp->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
fragments).</div>
<div><br>
</div>
<div>Some AVPs do have data and have a format
that looks valid.</div>
<div><br>
</div>
<div>Some AVPs looks corrupted. For example, I
found an AVP with same ID as the AVPs without
data, but avp->data == 0x8000 which looks
completely wrong.</div>
<div><br>

I don't know what exactly
might cause the leak. What
you can do is to try to
get a core dump (using
tools like gcore) during
low (or unexisting)
traffic and try to see
what do the AVPs that are
leaking contain. Are you
using QM debug?<br>
