Hi, we've come around to test again what happens if we set 'core.shmem' to a size larger than 4G. The original issue has been reported here #2824. We are running Kamailio 5.6 at commit `24989241cfc58c6ba47d48c9a86921251f4ba235` We are querying the `core.shmen` parameter via RPC and getting the following response from the server: ``` <?xml version="1.0"?> <methodResponse> <params> <param> <value><struct><member><name>total</name><value><int>-80</int></value></member><member><name>free</name><value><int>-66333776</int></value></member><member><name>used</name><value><int>63570392</int></value></member><member><name>real_used</name><value><int>66333696</int></value></member><member><name>max_used</name><value><int>68268896</int></value></member><member><name>fragments</name><value><int>2560</int></value></member></struct> </value> </param> </params> </methodResponse> ``` As you can see, the issue still persists.
