Hello,<br>
<br>
I looked quickly to the core and seems ok, I will check the
accounting later.<br>
<br>
Do you simply account $ai or is any other attribute related to it?<br>
<br>
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.<br>
<br>
Cheers,<br>

<div>I'm seeing a possible leak in parsing the

in kamailio-3.3.4.</div>

<div>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:</div>

<div>I am currently using the header through $ai for xlog
statements, the accounting module and a validity check (if
(!($(ai{uri.user}) =~ "^\+[1-9]+")) {...}).</div>
<div><br>
</div>
<div>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.</div>
