On a restart (i.e. rtpengine's mod_destroy() is called), rtpengine_hash_table_destroy() is called which frees the entire shm hashtable.
Possible limitations: - overhead added by the rtpengine hashlock (i.e. decrease in calls/sec rate) - more shm used (i.e. one has to increase the shm using kamailio's "-m" parameter)
What is the current known limitation for kamailio (calls/sec) ?
