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,

Hi César,
normally it should work here as in the old version. Do you compiled the new
version also with memory debug enabled and enabled also the appropriate
logging in the configuration?
build:
make cfg mode=debug MEMDBG=1
make all
cfg:
memlog=1
memdbg=1
Cheers,
Henning

New subject: Problem with debug memory: kill -SIGUSR1 doesn't work fine
Hello Henning.
Yes, I made both things. The only thing is that I have the next configuration:
debug=5
log_stderror=no
memdbg=3
memlog=3
But it worked in the previous version, so it should work now also (or that I suppose).
Really I think that's not the problem, because the debug for the shared memory and the
package memory of the principal thread appears, so it should be in other place (or I'm
wrong in my supposes and I should configure the Kamailio in another way).
Regards,
César Pinto (2439)
