Hi,
I'm seeing a possible leak in parsing the P-Asserted-Identity, and possibly
P-Preferred-Identity headers in kamailio-3.3.4.
I have a server running in which one thread has currently most of the 8 MB
private memory allocated. At restart qm_sums reports parse_pai.c as sitting
on most of the memory:
Apr 16 16:38:58 gws1 /usr/sbin/kamailio[9398]: INFO: qm_status: heap size=
8388608
Apr 16 16:38:58 gws1 /usr/sbin/kamailio[9398]: INFO: qm_status: used=
5369240, used+overhead=6417216, free=1971392
[...]
Apr 16 16:39:03 gws1 /usr/sbin/kamailio[9398]: INFO: qm_sums: count= 6198
size= 4721776 bytes from <core>: parse_pai.c: parse_pai_header(58)
I am currently using the header through $ai for xlog statements, the
accounting module and a validity check (if (!($(ai{uri.user}) =~
"^\+[1-9]+")) {...}).
>From digging through the logs it could seem like this happens when using
$ai in the accounting module. I'll try removing it from accounting
(log_extra) and see if it stops leaking.
