OK. Can you run the tests for a while and then execute:
kamctl rpc corex.pkg_summary idx 1
The value for idx should be the kamailio process expected to handle sip
traffic. If it is mostly udp and the first socket is the corresponding
udp socket, then the value 1, like above, is ok. If it is tcp/tls or you
have different listen parameters on udp, see the processes index with:
kamctl ps
It should not be required to wait till you get out of memory errors, but
be sure you run it long enough to have many accounting records written
by the process that is going to print the pkg summary. You can
eventually set the children to 1 or 2, to "force" traffic via a smaller
group of processes.
Cheers,
Daniel
