Thank you!
I will test this on my 4.0.4 setup and report back how it works.
Thank you,

I pushed a patch to master branch, hopefully fixing the leak:
- http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=7fb8c88c...
Before backporting, I need to have it tested and be sure is not having side effects.
For 4.0.x, if you installed from sources, either try to cherry pick the commit via git or edit the file:
modules/dispatcher/dispatch.c
and replace existing function destroy_list(...) with:
void destroy_list(int list_id) { ds_set_t *sp = NULL; ds_set_t *sp1 = NULL; ds_dest_t *dest = NULL;
sp = ds_lists[list_id];
while(sp) { sp1 = sp->next; for(dest = sp->dlist; dest!= NULL; dest=dest->next) { if(dest->uri.s!=NULL) { shm_free(dest->uri.s); dest->uri.s = NULL; } } if (sp->dlist != NULL) shm_free(sp->dlist); shm_free(sp); sp = sp1; }
ds_lists[list_id] = NULL; }
Let me know the results and if all ok, I will backport.

Short note to say that last log you sent had more leads, and apparently there is a leak at least in 4.0.
I need a bit more time to look at it and check if still on master and 4.1 (hopefully event later today) - I will come back with an update about it soon.

I didn't get the chance to look over the previous email, I will do it soon.

Here are the memory statistics; additionally, I can see the virtual memory has ballooned up to 400mb again.
shmem:fragments = 2378 shmem:free_size = 209840 shmem:max_used_size = 268393216 shmem:real_used_size = 268225616 shmem:total_size = 268435456 shmem:used_size = 220534792

I have about 460 destination sets. In each set I could have from 1 address up to 6.
When I took that initial memory log, Kamailio had been restarted shortly beforehand. I just took another one after the system had decayed so Kamailio was responding to Invites with "SIP/2.0 500 No error (2/SL)." (exhibiting the issue after a few days) and the log is about 400Mb! I'll attach a small snippet. Seems to be going on and on about the dispatcher module.

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).
Some more questions: - how many destination sets (groups) do you have? Can you estimate the minimum and maximum addresses in a set? - 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?

For dispatcher, I'm using a database that contains about 700 records.
A reload is performed via cronjob every 5 minutes. The command being used is:
kamctl dispatcher reload
Thanks, -Tim
