[SR-Users] Re: Kamailio - could not allocate private memory from pkg pool

6 Jun 2023

Mainly if I am looking at the private memory usage , it keeps
increasing very slowly but does not go back even after the calls are
literally zero. I suspect some UDP listener process are not releasing
the memory.

If I consider that my kamailio cfg and lua code has problem with
variables or something , I want to understand how it works when calls
are released. My understanding is usage should be minimum when calls
are released. Looking for feedback please?

[roottmp]# kamcmd pkg.stats |grep real_used
        real_used: 836144
        real_used: 1017328
        real_used: 1028656

        real_used: 1168552
        real_used: 1235528
        real_used: 917904

For short term I increase the pvt memory allocation or keep restarting
kamailio after every week or fortnight but I am looking for more
stable solution. I am using kamailio 5.5.3
