<tt>Hi, Mickael!<br>
<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>
<br>

If you do not have any SIP message

still have AVPs in memory....well,
it looks like a leak to me.<br>

What OpenSIPS version do you have ?<br>

<tt>What means
"a lot" :) ?
I'm asking as
if you have
100
transactions
in memory
(when doing
shutdown) and
you use ~10
AVPs per
INVITE in
script ->
you have 1000
AVPs in mem.</tt><br>
<br>
<tt>When doing
the shutdown,
are any
transaction in
memory ? (with
no active
transactions
in mem, there
are no AVPs in
mem).</tt><br>
