Some modules (e.g. carrierroute) can allocate quite large shared memory segments during startup, and it should work ok.

Previously, the would be smaller chunks(100 bytes at most) shm_malloced during message processing. I have observed significant runtime performance degradation from just this single change. I would appreciate any suggestions/thoughts you might have. Below are some the relevant details. OS:Alpine Linux RAM: 16GB Configured Shared memory: 4GB shm_force_alloc=1 Typical shared memory usage: 1.5GB System swapping is disabled, also observed during load testing that no mem is getting swapped. _______________________________________________ Kamailio (SER) - Development Mailing List sr-dev(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-dev
