Hello! Please, tell me. Opensips for some reason does not release shared memory (shmem), it was tested as in the documentation "https://www.opensips.org/Documentation/TroubleShooting-OutOfMem". Waited more than 20 minutes. Now I want to get a memory dump. I tried the same results on versions 2.2.5 and 2.3.1. Set for comparison kamailio, with a similar configuration, the memory is freed immediately, once the call is completed. What could be the problem ? Opensips v.2.3.1 OC CentOS 7 (virtual machine) At startup
