<p>Thanks for having a look into it. We did compile with system memory and use valgrind following the tips on dedicated page <a href="https://www.kamailio.org/wiki/tutorials/troubleshooting/memory" rel="nofollow">https://www.kamailio.org/wiki/tutorials/troubleshooting/memory</a></p>
<p>Unfortunately this gave no more clues (though it is possible I used it badly because it was the first time I used such tools).</p>
<p>We removed totally DMQ module from our Kamailios anyhow.<br>
We replaced it with a solution based on mqueue/http_async_client modules.</p>
<p>This issue can be closed as I am no more able to help in investigating further.<br>
Thank you.</p>
