Hello,
We had been experiencing memory leaks issues with our Kamailio deployment. Some of the
process started to use all their assigned memory and arises allocation memory errors.
Using the "kill -SIGUSR1" as explained in the Kamailio wiki and found the
problem:

We saw there was several core memory leaks resolved in the 3.0.3 version (we had the
3.0.2), so we decided to upgrade to that version. Now I was trying to check the memory
status of the process (in order to see if the problem is arising again) with "kill
-SIGUSR1" but now only show the memory status of the shm and the memory of the
attendant process (the one who launch the other ones). I had tried to send the signal to
each of the son process but I see nothing in the log.
Is this a new bug or is that there is other new way to see the memory status of the
processes?
Thanks in advance,
