[OpenSIPS-Users] Memory usage/leak - Opensips 3.1.13

[M S]

I will rephrase my question maybe someone has any ideas If I check memory
usage with pmap for highest using opensips process:
total kB         10774396 4579784 4564420
And this is the same as what top shows, around 4.5G memory usage.
If I use opensips-cli -x mi mem_pkg_dump for the same PID: heap size=
4294967296 used= 48336024, used+overhead=106291088, free=4188676208
And these numbers do not match. If pkg memory for this process is 48M as it
says, what is using 4.5G?
opensips parameters were -m 2G -M 4G
