[OpenSIPS-Users] Does not release shared memory

[Evgeniy G.]

Now I'm testing the server under load, 600 calls per minute and watching the
situation. I have only two sockets in the configuration:
listen = udp: 10.2.1.61: 7062
listen = udp: ХХ.ХХ.ХХХ.XXX: 7062
In the children parameter the value 2 is specified. But I can not understand
why 18 processes are created at startup ?... It's interesting that only two
of them take a role in the processing of calls, why? ... I found this out,
because of the decrease in two processes (pkmem:4 and pkmem:5) of pkg memory
.
Please explain the work with pkg memory when it is released.
I watched the server for 3 hours under load and 1 hour without, as a result,
on two processes the free private memory (pkmem) was rectilinearly reduced.
After testing, without restarting the server, private memory (pkgmem) is not
released, is it the way it should be?
