Hello,<br>
<br>
I tried to reproduce the scenario, but couldn't get the leak, might
be specific for your config and use case.<br>
<br>
Can you try the next steps, in order to check there is indeed a
leak:<br>
<br>
- use kamailio 4.2<br>
- set memlog parameter in kamailio.cfg to a lower value than debug
parameter (e.g., memlog=1)<br>
- start kamailio and do the tests you expect to lead to the issue<br>
- stop sending traffic to kamailio (no more calls)<br>
- issue the command "kamcmd corex.shm_summary" and look in the
syslog file, grab the memory dump summary messages<br>
- wait for 3 minutes (still with no traffic) and issue again
"kamcmd corex.shm_summary", grab again the summary from the syslog<br>
- send here the messages from the two summaries<br>
<br>
Cheers,<br>
Daniel<br>
