<p>Hello,</p>
<p>are you using accounting to generate CDRs with dialog module
(records in acc_cdrs table)? Or only for getting the event records
in the acc table?</p>
<p>Cheers,<br>
Daniel<br>

<br>
as I am not a user of dialog variables, I am turning
to community to ask<br>
for help testing the current master branch with
configurations that make<br>
use of dialog variables and acc dialog-based cdr
generation.<br>
<br>
With a few reports of issues related to dialog modules
and unexpected<br>
crashes, I looked over the code and noticed that the
access of the value<br>
for dialog variables was not protected, making them
vulnerable of<br>
invalid memory access in case of the variable was
updated by another<br>
process or dialog was terminated.<br>
<br>
I introduced a couple of new functions to try to cover
different use<br>
cases of getting the dlg variable values, dialog
management code was not<br>
affected, but given that these commits need to be
backported to stable<br>
branch (5.6), I want to get proper feedback from
community that things<br>
work fine.<br>
<br>
A previous attempt of a simpler fix was not enough,
having side effects<br>
to acc module for dialog-based cdr generation, because
it was keeping<br>
referenced to many dlg variables at the same time.<br>
<br>
In short, it would be appreciated any feedback on
testing dialog and acc<br>
with dialog-based cdr generation using git master
branch.<br>

<div>I usually leave a commit load test running for 2

<div>I reverted 2 of the load test envs to previous kamailio
5.6 commit 61e86a1f502388ffd4dce6e52811ba640337c813 and
restarted the load tests, then again, kamailio master commit
6f400a8074fe60916867596431ca26dff00435d1 started to write
the above logs but this doesn't happen with 5.6.</div>
