I pushed a patch to master branch, hopefully fixing the leak:<br>

<br>
Before backporting, I need to have it tested and be sure is not
having side effects.<br>
<br>
For 4.0.x, if you installed from sources, either try to cherry pick
the commit via git or edit the file:<br>
<br>
modules/dispatcher/dispatch.c <br>
<br>
and replace existing function destroy_list(...) with:<br>
<br>
void destroy_list(int list_id)<br>
{<br>
ds_set_t *sp = NULL;<br>
ds_set_t *sp1 = NULL;<br>
ds_dest_t *dest = NULL;<br>
<br>
sp = ds_lists[list_id];<br>
<br>
while(sp)<br>
{<br>
sp1 = sp->next;<br>
for(dest = sp->dlist; dest!= NULL; dest=dest->next)<br>
{<br>
if(dest->uri.s!=NULL)<br>
{<br>
shm_free(dest->uri.s);<br>
dest->uri.s = NULL;<br>
}<br>
}<br>
if (sp->dlist != NULL)<br>
shm_free(sp->dlist);<br>
shm_free(sp);<br>
sp = sp1;<br>
}<br>
<br>
ds_lists[list_id] = NULL;<br>
}<br>
<br>
Let me know the results and if all ok, I will backport.<br>
<br>
Cheers,<br>

say that last log you sent had more leads, and apparently
there is a leak at least in 4.0.<br>

I need a bit more time to look at it and check if still on

back with an update about it soon.<br>

<p class="MsoNormal" style="margin-bottom:12.0pt">Looking at
the logs, there are 1336 URIs, which seems ok given your
numbers, because the module keeps also the previous set of
records (needed because at reload time there can be
kamailio worker processes using the records -- perhaps we
can improve a bit here, I will review the current reload
code a bit, since it was a contribution from another
developer quite long time ago).<br>
<br>
Some more questions:<br>
- how many destination sets (groups) do you have? Can you
estimate the minimum and maximum addresses in a set?<br>
- when did you take the memory log? In other words, for
how long was kamailio running? Did you wait enough to
notice the steady increase of memory usage?<br>
