[OpenSIPS-Users] Does not release shared memory

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

[root at new-centos7 ~]# /usr/local/opensips225/sbin/opensipsctl start

I made one call.
