<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>
<br>
Best regards,<br>

<div>I have some news.</div>

<div><br>
</div>
<div>Is there a specific handling for those AVPs?</div>
<div><br>

<div>Here is how I use it:</div>
<div><br>
</div>
<div>static str bavp_msgops_flags =
str_init("$bavp(_msgops_bflags)");<br>
</div>
<div>pv_spec_t bavp_msgops_flags_spec;<br>

</div>
<div>In mod_init:</div>
<div><br>
</div>
<div>
<div>if (parse_store_bavp(&bavp_msgops_flags,
&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> LM_ERR("Fail to set branch flags AVP.\n");</div>
<div> return -1;</div>
<div>}</div>
</div>
<div><br>
</div>
<div>Sometimes, I do the following to get the branch AVP value:</div>
<div><br>
</div>
<div>
<div>if (pv_get_spec_value(rpl, &bavp_msgops_flags_spec,
&b_flags_val) != 0) {</div>

Not sure why the signal is triggered. But what you could
do is to replicate the behavior of the function until
you find the proper id.<br>

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
the AVP is populated. Is it done for each
message? Timer based?<br>
If I were you, I'd continue tracing the
name of the AVPs and checking where they
are populated.<br>

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>
<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>
