Whern I check the shmem usage I see the data take about 0.8G out of 4G i set on shmem. When i reload the data while kamailio is running, the memory usage rises to 1.3G and stays there (the second and next reloads stays on 1.3G as well). Why doesn't it return to 0.8G after the reload is completed? can you send the statistics related to shmem? kamctl fifo get_statistics shmem: There are different values there, some usage come from overhead of memory chunks management.
