Hello,

I had added $ai to acc log_extra like this:

modparam("acc", "log_extra",

    "dst_ouser=$tU;dst_user=$rU;dst_domain=$rd"

    "p_asserted_identity=$ai;remote_party_id=$re")

Once I commented out the last line, the leak vanished.

I'll test the avp intermediary in the next few days.

ok, I will look over acc module for this case.

Do you still have the xlog lines printing these variables?

Cheers,
Daniel

Hello,

I looked quickly to the core and seems ok, I will check the accounting later.

Do you simply account $ai or is any other attribute related to it?

If you have time to test, can you put the $ai in an avp during the request processing and account that avp? If the leak is not shown anymore in that case, it narrows down a lot where to look at.

Cheers,
Daniel

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.
